 ** v0.2.0 - [2019-04-14]
+*** Added
+ - A selection-based unit converter which allows you to select two units, input a value, and convert.
+ - The UnitDatabase now stores dimensions.
+ - A system to parse mathematical expressions, used to parse unit expressions.
+ - You can now add and subtract in unit expressions!
+ - Instructions for obtaining unit instances are provided in the relevant classes
+ - The UnitPrefix interface now provides default times, dividedBy and toExponent methods.

-	 * A map for units that allows the use of prefixes.
-	 * <p>
-	 * As this map implementation is intended to be used as a sort of "augmented view" of a unit and prefix map, it is
-	 * unmodifiable but instead reflects the changes to the maps passed into it. Do not edit this map, instead edit the
-	 * maps that were passed in during construction.
-	 * </p>
-	 * <p>
-	 * The rules for applying prefixes onto units are the following:
-	 * <ul>
-	 * <li>Prefixes can only be applied to linear units.</li>
-	 * <li>Before attempting to search for prefixes in a unit name, this map will first search for a unit name. So, if
-	 * there are two units, "B" and "AB", and a prefix "A", this map will favour the unit "AB" over the unit "B" with
-	 * the prefix "A", even though they have the same string.</li>
-	 * <li>Longer prefixes are preferred to shorter prefixes. So, if you have units "BC" and "C", and prefixes "AB" and
-	 * "A", inputting "ABC" will return the unit "C" with the prefix "AB", not "BC" with the prefix "A".</li>
-	 * </ul>
-	 * </p>
-	 * <p>
-	 * This map is infinite in size if there is at least one unit and at least one prefix. If it is infinite, some
-	 * operations that only work with finite collections, like converting name/entry sets to arrays, will throw an
-	 * {@code IllegalStateException}.
-	 * </p>
-	 * <p>
-	 * Because of ambiguities between prefixes (i.e. kilokilo = mega), {@link #containsValue} and {@link #values()}
-	 * currently ignore prefixes.

+	 * maps that were passed in during construction.
+	 * </p>
+	 * <p>
+	 * The rules for applying prefixes onto units are the following:
+	 * <ul>
+	 * <li>Prefixes can only be applied to linear units.</li>
+	 * <li>Before attempting to search for prefixes in a unit name, this map will first search for a unit name. So, if
+	 * there are two units, "B" and "AB", and a prefix "A", this map will favour the unit "AB" over the unit "B" with
+	 * the prefix "A", even though they have the same string.</li>
+	 * <li>Longer prefixes are preferred to shorter prefixes. So, if you have units "BC" and "C", and prefixes "AB" and
+	 * "A", inputting "ABC" will return the unit "C" with the prefix "AB", not "BC" with the prefix "A".</li>
+	 * </ul>
+	 * </p>
+	 * <p>
+	 * This map is infinite in size if there is at least one unit and at least one prefix. If it is infinite, some
+	 * operations that only work with finite collections, like converting name/entry sets to arrays, will throw an
+	 * {@code IllegalStateException}.
+	 * </p>
+	 * <p>
+	 * Because of ambiguities between prefixes (i.e. kilokilo = mega), {@link #containsValue} and {@link #values()}
+	 * currently ignore prefixes.

Subject: Multiplication between a value and a unit now has precedence.

Example, 3 m / 2 s = (3 m) / (2 s)
This change also makes "3m" a valid expression.

+<h1 class="title">How This API Document Is Organized</h1>
+<div class="subTitle">This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.</div>
+</div>
+<div class="contentContainer">
+<ul class="blockList">
+<li class="blockList">
+<h2>Overview</h2>
+<p>The <a href="overview-summary.html">Overview</a> page is the front page of this API document and provides a list of all packages with a summary for each.  This page can also contain an overall description of the set of packages.</p>
+</li>
+<li class="blockList">
+<h2>Package</h2>
+<p>Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain six categories:</p>
+<ul>
+<li>Interfaces (italic)</li>
+<li>Classes</li>
+<li>Enums</li>
+<li>Exceptions</li>
+<li>Errors</li>
+<li>Annotation Types</li>
+</ul>
+</li>
+<li class="blockList">
+<h2>Class/Interface</h2>
+<p>Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:</p>
+<ul>
+<li>Class inheritance diagram</li>
+<li>Direct Subclasses</li>
+<li>All Known Subinterfaces</li>
+<li>All Known Implementing Classes</li>
+<li>Class/interface declaration</li>
+<li>Class/interface description</li>
+</ul>
+<ul>
+<li>Nested Class Summary</li>
+<li>Field Summary</li>
+<li>Constructor Summary</li>
+<li>Method Summary</li>
+</ul>
+<ul>
+<li>Field Detail</li>
+<li>Constructor Detail</li>
+<li>Method Detail</li>
+</ul>
+<p>Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</p>
+</li>
+<li class="blockList">
+<h2>Annotation Type</h2>
+<p>Each annotation type has its own separate page with the following sections:</p>
+<ul>
+<li>Annotation Type declaration</li>
+<li>Annotation Type description</li>
+<li>Required Element Summary</li>
+<li>Optional Element Summary</li>
+<li>Element Detail</li>
+</ul>
+</li>
+<li class="blockList">
+<h2>Enum</h2>
+<p>Each enum has its own separate page with the following sections:</p>
+<ul>
+<li>Enum declaration</li>
+<li>Enum description</li>
+<li>Enum Constant Summary</li>
+<li>Enum Constant Detail</li>
+</ul>
+</li>
+<li class="blockList">
+<h2>Use</h2>
+<p>Each documented package, class and interface has its own Use page.  This page describes what packages, classes, methods, constructors and fields use any part of the given class or package. Given a class or interface A, its Use page includes subclasses of A, fields declared as A, methods that return A, and methods and constructors with parameters of type A.  You can access this page by first going to the package, class or interface, then clicking on the "Use" link in the navigation bar.</p>
+</li>
+<li class="blockList">
+<h2>Tree (Class Hierarchy)</h2>
+<p>There is a <a href="overview-tree.html">Class Hierarchy</a> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.</p>
+<ul>
+<li>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.</li>
+<li>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</li>
+</ul>
+</li>
+<li class="blockList">
+<h2>Deprecated API</h2>
+<p>The <a href="deprecated-list.html">Deprecated API</a> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</p>
+</li>
+<li class="blockList">
+<h2>Index</h2>
+<p>The <a href="index-files/index-1.html">Index</a> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</p>
+</li>
+<li class="blockList">
+<h2>Prev/Next</h2>
+<p>These links take you to the next or previous class, interface, package, or related page.</p>
+</li>
+<li class="blockList">
+<h2>Frames/No Frames</h2>
+<p>These links show and hide the HTML frames.  All pages are available with or without frames.</p>
+</li>
+<li class="blockList">
+<h2>All Classes</h2>
+<p>The <a href="allclasses-noframe.html">All Classes</a> link shows all classes and interfaces except non-static nested types.</p>
+</li>
+<li class="blockList">
+<h2>Serialized Form</h2>
+<p>Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.</p>
+</li>
+<li class="blockList">
+<h2>Constant Field Values</h2>
+<p>The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.</p>
+</li>
+</ul>
+<span class="emphasizedPhrase">This help file applies to API documentation generated using the standard doclet.</span></div>

+ * Decompress `data` with inflate/ungzip and `options`. Autodetect

+ *
+ * Supported options are:
+ *

+ * - `raw` (Boolean) - say that we work with raw stream, if you don't wish to specify
+ *   negative windowBits implicitly.
+ * - `to` (String) - if equal to 'string', then result will be converted
+ *   from utf8 to utf16 (javascript) string. When string output requested,
+ *   chunk length can differ from `chunkSize`, depending on content.
+ *
+ *
+ * ##### Example:
+ *
+ * ```javascript
+ * var pako = require('pako')
+ *   , input = pako.deflate([1,2,3,4,5,6,7,8,9])
+ *   , output;
+ *
+ * try {

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state.mode === LEN
+        strm.avail_in >= 6
+        strm.avail_out >= 258
+        start >= strm.avail_out

+

+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm.avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm.avail_out >= 258 for each loop to avoid checking for

+   Process a set of code lengths to create a canonical Huffman code.  The

+   symbols 0..codes-1.  The Huffman code is generated by first sorting the
+   symbols by length from short to long, and retaining the symbol order
+   for codes with equal lengths.  Then the code starts with all zero bits
+   for the first code of the shortest length, and the codes are integer
+   increments for the same length, and zeros are appended as the length
+   increases.  For the deflate format, these bits are stored backwards
+   from their more natural integer increment ordering, and so when the
+   decoding tables are built in the large loop below, the integer codes
+   are incremented backwards.
+
+   This routine assumes, but does not check, that all of the entries in
+   lens[] are in the range 0..MAXBITS.  The caller must assure this.
+   1..MAXBITS is interpreted as that code length.  zero means that that
+   symbol does not occur in this code.
+
+   The codes are sorted by computing a count of codes for each length,
+   creating from that a table of starting indices for each length in the
+   sorted table, and then entering the symbols in order in the sorted
+   table.  The sorted table is work[], with that space being provided by
+   the caller.
+
+   The length counts are used for other purposes as well, i.e. finding
+   the minimum and maximum length codes, determining if there are any
+   codes at all, checking for a valid set of lengths, and looking ahead
+   at length counts to determine sub-table sizes when building the

+ All of the collections in this class are "views" of the provided collections. They are mutable if the provided
+ collections are mutable, they allow null if the provided collections allow null, they will reflect changes in the

+ The modification operations will always run the corresponding operations, even if the conditional existence
+ collection doesn't change. For example, if you have a set that ignores even numbers, add(2) will still add a 2 to the
+ backing set (but the conditional existence set will say it doesn't exist).

+<div class="block">A map for units that allows the use of prefixes.
+ <p>
+ As this map implementation is intended to be used as a sort of "augmented view" of a unit and prefix map, it is
+ unmodifiable but instead reflects the changes to the maps passed into it. Do not edit this map, instead edit the
+ maps that were passed in during construction.
+ </p>
+ <p>
+ The rules for applying prefixes onto units are the following:
+ <ul>
+ <li>Prefixes can only be applied to linear units.</li>
+ <li>Before attempting to search for prefixes in a unit name, this map will first search for a unit name. So, if
+ there are two units, "B" and "AB", and a prefix "A", this map will favour the unit "AB" over the unit "B" with
+ the prefix "A", even though they have the same string.</li>
+ <li>Longer prefixes are preferred to shorter prefixes. So, if you have units "BC" and "C", and prefixes "AB" and
+ "A", inputting "ABC" will return the unit "C" with the prefix "AB", not "BC" with the prefix "A".</li>
+ </ul>
+ </p>
+ <p>
+ This map is infinite in size if there is at least one unit and at least one prefix. If it is infinite, some
+ operations that only work with finite collections, like converting name/entry sets to arrays, will throw an
+ <code>IllegalStateException</code>.
+ </p>
+ <p>
+ Because of ambiguities between prefixes (i.e. kilokilo = mega), <a href="#containsValue(java.lang.Object)"><code>containsValue(java.lang.Object)</code></a> and <a href="#values()"><code>values()</code></a>
+ currently ignore prefixes.

-<h1 class="title">How This API Document Is Organized</h1>
-<div class="subTitle">This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.</div>
-</div>
-<div class="contentContainer">
-<ul class="blockList">
-<li class="blockList">
-<h2>Overview</h2>
-<p>The <a href="overview-summary.html">Overview</a> page is the front page of this API document and provides a list of all packages with a summary for each.  This page can also contain an overall description of the set of packages.</p>
-</li>
-<li class="blockList">
-<h2>Package</h2>
-<p>Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain six categories:</p>
-<ul>
-<li>Interfaces (italic)</li>
-<li>Classes</li>
-<li>Enums</li>
-<li>Exceptions</li>
-<li>Errors</li>
-<li>Annotation Types</li>
-</ul>
-</li>
-<li class="blockList">
-<h2>Class/Interface</h2>
-<p>Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:</p>
-<ul>
-<li>Class inheritance diagram</li>
-<li>Direct Subclasses</li>
-<li>All Known Subinterfaces</li>
-<li>All Known Implementing Classes</li>
-<li>Class/interface declaration</li>
-<li>Class/interface description</li>
-</ul>
-<ul>
-<li>Nested Class Summary</li>
-<li>Field Summary</li>
-<li>Constructor Summary</li>
-<li>Method Summary</li>
-</ul>
-<ul>
-<li>Field Detail</li>
-<li>Constructor Detail</li>
-<li>Method Detail</li>
-</ul>
-<p>Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</p>
-</li>
-<li class="blockList">
-<h2>Annotation Type</h2>
-<p>Each annotation type has its own separate page with the following sections:</p>
-<ul>
-<li>Annotation Type declaration</li>
-<li>Annotation Type description</li>
-<li>Required Element Summary</li>
-<li>Optional Element Summary</li>
-<li>Element Detail</li>
-</ul>
-</li>
-<li class="blockList">
-<h2>Enum</h2>
-<p>Each enum has its own separate page with the following sections:</p>
-<ul>
-<li>Enum declaration</li>
-<li>Enum description</li>
-<li>Enum Constant Summary</li>
-<li>Enum Constant Detail</li>
-</ul>
-</li>
-<li class="blockList">
-<h2>Use</h2>
-<p>Each documented package, class and interface has its own Use page.  This page describes what packages, classes, methods, constructors and fields use any part of the given class or package. Given a class or interface A, its Use page includes subclasses of A, fields declared as A, methods that return A, and methods and constructors with parameters of type A.  You can access this page by first going to the package, class or interface, then clicking on the "Use" link in the navigation bar.</p>
-</li>
-<li class="blockList">
-<h2>Tree (Class Hierarchy)</h2>
-<p>There is a <a href="overview-tree.html">Class Hierarchy</a> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.</p>
-<ul>
-<li>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.</li>
-<li>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</li>
-</ul>
-</li>
-<li class="blockList">
-<h2>Deprecated API</h2>
-<p>The <a href="deprecated-list.html">Deprecated API</a> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</p>
-</li>
-<li class="blockList">
-<h2>Index</h2>
-<p>The <a href="index-files/index-1.html">Index</a> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</p>
-</li>
-<li class="blockList">
-<h2>Prev/Next</h2>
-<p>These links take you to the next or previous class, interface, package, or related page.</p>
-</li>
-<li class="blockList">
-<h2>Frames/No Frames</h2>
-<p>These links show and hide the HTML frames.  All pages are available with or without frames.</p>
-</li>
-<li class="blockList">
-<h2>All Classes</h2>
-<p>The <a href="allclasses-noframe.html">All Classes</a> link shows all classes and interfaces except non-static nested types.</p>
-</li>
-<li class="blockList">
-<h2>Serialized Form</h2>
-<p>Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.</p>
-</li>
-<li class="blockList">
-<h2>Constant Field Values</h2>
-<p>The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.</p>
-</li>
-</ul>
-<span class="emphasizedPhrase">This help file applies to API documentation generated using the standard doclet.</span></div>

-//	Implementation Summary
-//
-//	1. Enforce API surface and semantic compatibility with 1.9.x branch
-//	2. Improve the module's maintainability by reducing the storage
-//		paths to a single mechanism.
-//	3. Use the same single mechanism to support "private" and "user" data.
-//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
-//	5. Avoid exposing implementation details on user objects (eg. expando properties)
-//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

-//	Implementation Summary
-//
-//	1. Enforce API surface and semantic compatibility with 1.9.x branch
-//	2. Improve the module's maintainability by reducing the storage
-//		paths to a single mechanism.
-//	3. Use the same single mechanism to support "private" and "user" data.
-//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
-//	5. Avoid exposing implementation details on user objects (eg. expando properties)
-//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

- * Additional options, for internal needs:
- *
- * - `chunkSize` - size of generated data chunks (16K by default)
- * - `raw` (Boolean) - do raw deflate
- * - `gzip` (Boolean) - create gzip wrapper
- * - `to` (String) - if equal to 'string', then result will be "binary string"
- *    (each char code [0..255])
- * - `header` (Object) - custom header for gzip
- *   - `text` (Boolean) - true if compressed data believed to be text
- *   - `time` (Number) - modification time, unix timestamp
- *   - `os` (Number) - operation system code
- *   - `extra` (Array) - array of bytes with extra data (max 65536)
- *   - `name` (String) - file name (binary string)
- *   - `comment` (String) - comment (binary string)
- *   - `hcrc` (Boolean) - true if header crc should be added

- *
- * Sends input data to deflate pipe, generating [[Deflate#onData]] calls with

-   Decode literal, length, and distance codes and write out the resulting
-   literal and match bytes until either not enough input or output is
-   available, an end-of-block is encountered, or a data error is encountered.
-   When large enough input and output buffers are supplied to inflate(), for
-   example, a 16K input buffer and a 64K output buffer, more than 95% of the
-   inflate execution time is spent in this routine.
-
-   Entry assumptions:
-
-        state.mode === LEN
-        strm.avail_in >= 6
-        strm.avail_out >= 258
-        start >= strm.avail_out
-        state.bits < 8
-
-   On return, state.mode is one of:
-
-        LEN -- ran out of enough output space or enough available input
-        TYPE -- reached end of block code, inflate() to interpret next block
-        BAD -- error in block data
-
-   Notes:
-
-    - The maximum input bits used by a length/distance pair is 15 bits for the
-      length code, 5 bits for the length extra, 15 bits for the distance code,
-      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
-      Therefore if strm.avail_in >= 6, then there is enough input to avoid
-      checking for available input while decoding.
-
-    - The maximum bytes that a single length/distance pair can output is 258
-      bytes, which is the maximum length that can be coded.  inflate_fast()
-      requires strm.avail_out >= 258 for each loop to avoid checking for
-      output space.

-   Process a set of code lengths to create a canonical Huffman code.  The
-   code lengths are lens[0..codes-1].  Each length corresponds to the
-   symbols 0..codes-1.  The Huffman code is generated by first sorting the
-   symbols by length from short to long, and retaining the symbol order
-   for codes with equal lengths.  Then the code starts with all zero bits
-   for the first code of the shortest length, and the codes are integer
-   increments for the same length, and zeros are appended as the length
-   increases.  For the deflate format, these bits are stored backwards
-   from their more natural integer increment ordering, and so when the
-   decoding tables are built in the large loop below, the integer codes
-   are incremented backwards.
-
-   This routine assumes, but does not check, that all of the entries in
-   lens[] are in the range 0..MAXBITS.  The caller must assure this.
-   1..MAXBITS is interpreted as that code length.  zero means that that
-   symbol does not occur in this code.
-
-   The codes are sorted by computing a count of codes for each length,
-   creating from that a table of starting indices for each length in the
-   sorted table, and then entering the symbols in order in the sorted
-   table.  The sorted table is work[], with that space being provided by
-   the caller.
-
-   The length counts are used for other purposes as well, i.e. finding
-   the minimum and maximum length codes, determining if there are any
-   codes at all, checking for a valid set of lengths, and looking ahead
-   at length counts to determine sub-table sizes when building the

-   Create and fill in decoding tables.  In this loop, the table being

-   bits off of the bottom.  For codes where len is less than drop + curr,
-   those top drop + curr - len bits are incremented through all values to
-   fill the table with replicated entries.
-
-   root is the number of index bits for the root table.  When len exceeds
-   root, sub-tables are created pointed to by the root entry with an index
-   of the low root bits of huff.  This is saved in low to check for when a
-   new sub-table should be started.  drop is zero when the root table is
-   being filled, and drop is root when sub-tables are being filled.
-
-   When a new sub-table is needed, it is necessary to look ahead in the
-   code lengths to determine what size sub-table is needed.  The length
-   counts are used for this, and so count[] is decremented as codes are
-   entered in the tables.
-
-   used keeps track of how many table entries have been allocated from the
-   provided *table space.  It is checked for LENS and DIST tables against

-   the initial root table size constants.  See the comments in inftrees.h
-   for more information.
-
-   sym increments through all symbols, and the loop terminates when
-   all codes of length max, i.e. all codes, have been processed.  This
-   routine permits incomplete codes, so another loop after this one fills
-   in the rest of the decoding tables with invalid code markers.

- All of the collections in this class are "views" of the provided collections. They are mutable if the provided
- collections are mutable, they allow null if the provided collections allow null, they will reflect changes in the
- provided collection, etc.
- <p>
- The modification operations will always run the corresponding operations, even if the conditional existence
- collection doesn't change. For example, if you have a set that ignores even numbers, add(2) will still add a 2 to the
- backing set (but the conditional existence set will say it doesn't exist).
- <p>
- The returned collections do <i>not</i> pass the hashCode and equals operations through to the backing collections,
- but rely on <code>Object</code>'s <code>equals</code> and <code>hashCode</code> methods. This is necessary to preserve the contracts
- of these operations in the case that the backing collections are sets or lists.
- <p>
- Other than that, <i>the only difference between the provided collections and the returned collections are that
- elements don't exist if they don't pass the provided condition</i>.</div>

-<div class="block">A map for units that allows the use of prefixes.
- <p>
- As this map implementation is intended to be used as a sort of "augmented view" of a unit and prefix map, it is
- unmodifiable but instead reflects the changes to the maps passed into it. Do not edit this map, instead edit the
- maps that were passed in during construction.
- </p>
- <p>
- The rules for applying prefixes onto units are the following:
- <ul>
- <li>Prefixes can only be applied to linear units.</li>
- <li>Before attempting to search for prefixes in a unit name, this map will first search for a unit name. So, if
- there are two units, "B" and "AB", and a prefix "A", this map will favour the unit "AB" over the unit "B" with
- the prefix "A", even though they have the same string.</li>
- <li>Longer prefixes are preferred to shorter prefixes. So, if you have units "BC" and "C", and prefixes "AB" and
- "A", inputting "ABC" will return the unit "C" with the prefix "AB", not "BC" with the prefix "A".</li>
- </ul>
- </p>
- <p>
- This map is infinite in size if there is at least one unit and at least one prefix. If it is infinite, some
- operations that only work with finite collections, like converting name/entry sets to arrays, will throw an
- <code>IllegalStateException</code>.
- </p>
- <p>
- Because of ambiguities between prefixes (i.e. kilokilo = mega), <a href="#containsValue(java.lang.Object)"><code>containsValue(java.lang.Object)</code></a> and <a href="#values()"><code>values()</code></a>
- currently ignore prefixes.

+	 * A map for units that allows the use of prefixes.
+	 * <p>
+	 * As this map implementation is intended to be used as a sort of "augmented
+	 * view" of a unit and prefix map, it is unmodifiable but instead reflects
+	 * the changes to the maps passed into it. Do not edit this map, instead edit
+	 * the maps that were passed in during construction.
+	 * </p>
+	 * <p>
+	 * The rules for applying prefixes onto units are the following:
+	 * <ul>
+	 * <li>Prefixes can only be applied to linear units.</li>
+	 * <li>Before attempting to search for prefixes in a unit name, this map will
+	 * first search for a unit name. So, if there are two units, "B" and "AB",
+	 * and a prefix "A", this map will favour the unit "AB" over the unit "B"
+	 * with the prefix "A", even though they have the same string.</li>
+	 * <li>Longer prefixes are preferred to shorter prefixes. So, if you have
+	 * units "BC" and "C", and prefixes "AB" and "A", inputting "ABC" will return
+	 * the unit "C" with the prefix "AB", not "BC" with the prefix "A".</li>
+	 * </ul>
+	 * </p>
+	 * <p>
+	 * This map is infinite in size if there is at least one unit and at least
+	 * one prefix. If it is infinite, some operations that only work with finite
+	 * collections, like converting name/entry sets to arrays, will throw an
+	 * {@code IllegalStateException}.
+	 * </p>
+	 * <p>
+	 * Because of ambiguities between prefixes (i.e. kilokilo = mega),
+	 * {@link #containsValue} and {@link #values()} currently ignore prefixes.

-	 * A map for units that allows the use of prefixes.
-	 * <p>
-	 * As this map implementation is intended to be used as a sort of "augmented
-	 * view" of a unit and prefix map, it is unmodifiable but instead reflects
-	 * the changes to the maps passed into it. Do not edit this map, instead edit
-	 * the maps that were passed in during construction.
-	 * </p>
-	 * <p>
-	 * The rules for applying prefixes onto units are the following:
-	 * <ul>
-	 * <li>Prefixes can only be applied to linear units.</li>
-	 * <li>Before attempting to search for prefixes in a unit name, this map will
-	 * first search for a unit name. So, if there are two units, "B" and "AB",
-	 * and a prefix "A", this map will favour the unit "AB" over the unit "B"
-	 * with the prefix "A", even though they have the same string.</li>
-	 * <li>Longer prefixes are preferred to shorter prefixes. So, if you have
-	 * units "BC" and "C", and prefixes "AB" and "A", inputting "ABC" will return
-	 * the unit "C" with the prefix "AB", not "BC" with the prefix "A".</li>
-	 * </ul>
-	 * </p>
-	 * <p>
-	 * This map is infinite in size if there is at least one unit and at least
-	 * one prefix. If it is infinite, some operations that only work with finite
-	 * collections, like converting name/entry sets to arrays, will throw an
-	 * {@code IllegalStateException}.
-	 * </p>
-	 * <p>
-	 * Because of ambiguities between prefixes (i.e. kilokilo = mega),
-	 * {@link #containsValue} and {@link #values()} currently ignore prefixes.

 ** What is it?
   This is a unit converter, which allows you to convert between different units, and includes a GUI which can read unit data from a file (using some unit math) and convert between units that you type in, and has a unit and prefix viewer to check the units that have been loaded in.
 ** Features
  - Convert between units and expressions of units
- - linear or base unit can use unit prefixes (including non-metric units!)
+ - linear or base units can use unit prefixes (including non-metric units!)
  - and prefixes are defined in an editable data file, in a simple and intuitive format.
  - Viewer and Prefix Viewer which allow you to search through all of the available units and prefixes and learn details about them.
  - All of SI included in default text file
@@ -65,11 +65,11 @@ Nonlinear units cannot:
  - use prefixes
  - be defined by unit files
 
-To define a nonlinear unit, make an anonymous inner type (or any other subclass) of AbstractUnit, and define the conversion methods.
+To define a nonlinear unit, make an anonymous inner type (or any other subclass) of Unit, and define the conversion methods.  You can do this easily using Unit's static methods.
 ** Unit and Prefix Viewers
 The unit and prefix viewers can be used to see the available units (without prefixes) and prefixes.  Upon opening them, you will see a list of units or prefixes on your left.  Using the text box above, the list can be filtered.  When a unit is clicked on, details about will be displayed on the right.
