     * @class Autolinker.HtmlTag
     * @extends Object
     *
     * Represents an HTML tag, which can be used to easily build/modify HTML tags programmatically.
     *
     * Autolinker uses this abstraction to create HTML tags, and then write them out as strings. You may also use
     * this class in your code, especially within a {@link Autolinker#replaceFn replaceFn}.
     *
     * ## Examples
     *
     * Example instantiation:
     *
     *     var tag = new Autolinker.HtmlTag( {
     *         tagName : 'a',
     *         attrs   : { 'href': 'http://google.com', 'class': 'external-link' },
     *         innerHtml : 'Google'
     *     } );
     *
     *     tag.toAnchorString();  // <a href="http://google.com" class="external-link">Google</a>
     *
     *     // Individual accessor methods
     *     tag.getTagName();                 // 'a'
     *     tag.getAttr( 'href' );            // 'http://google.com'
     *     tag.hasClass( 'external-link' );  // true
     *
     *
     * Using mutator methods (which may be used in combination with instantiation config properties):
     *
     *     var tag = new Autolinker.HtmlTag();
     *     tag.setTagName( 'a' );
     *     tag.setAttr( 'href', 'http://google.com' );
     *     tag.addClass( 'external-link' );
     *     tag.setInnerHtml( 'Google' );
     *
     *     tag.getTagName();                 // 'a'
     *     tag.getAttr( 'href' );            // 'http://google.com'
     *     tag.hasClass( 'external-link' );  // true
     *
     *     tag.toAnchorString();  // <a href="http://google.com" class="external-link">Google</a>
     *
     *
     * ## Example use within a {@link Autolinker#replaceFn replaceFn}
     *
     *     var html = Autolinker.link( "Test google.com", {
     *         replaceFn : function( match ) {
     *             var tag = match.buildTag();  // returns an {@link Autolinker.HtmlTag} instance, configured with the Match's href and anchor text
     *             tag.setAttr( 'rel', 'nofollow' );
     *
     *             return tag;
     *         }
     *     } );
     *
     *     // generated html:
     *     //   Test <a href="http://google.com" target="_blank" rel="nofollow">google.com</a>
     *
     *
     * ## Example use with a new tag for the replacement
     *
     *     var html = Autolinker.link( "Test google.com", {
     *         replaceFn : function( match ) {
     *             var tag = new Autolinker.HtmlTag( {
     *                 tagName : 'button',
     *                 attrs   : { 'title': 'Load URL: ' + match.getAnchorHref() },
     *                 innerHtml : 'Load URL: ' + match.getAnchorText()
     *             } );
     *
     *             return tag;

             *

             *     has at least one dot ('.') in it.
             * 2.  Group that matches a 'www.' prefixed URL. This is only matched if the
             *     'www.' text was not prefixed by a scheme (i.e.: not prefixed by
             *     'http://', 'ftp:', etc.)
             * 3.  A protocol-relative ('//') match for the case of a 'www.' prefixed
             *     URL. Will be an empty string if it is not a protocol-relative match.
             *     We need to know the character before the '//' in order to determine
             *     if it is a valid match or the // was in a string we don't want to
             *     auto-link.
             * 4.  Group that matches a known TLD (top level domain), when a scheme
             *     or 'www.'-prefixed domain is not matched.
             * 5.  A protocol-relative ('//') match for the case of a known TLD prefixed
             *     URL. Will be an empty string if it is not a protocol-relative match.

     * Parses an HTML string, calling the callbacks to notify of tags and text.
     *
     * ## History
     *
     * This file previously used a regular expression to find html tags in the input
     * text. Unfortunately, we ran into a bunch of catastrophic backtracking issues
     * with certain input text, causing Autolinker to either hang or just take a
     * really long time to parse the string.
     *
     * The current code is intended to be a O(n) algorithm that walks through
     * the string in one pass, and tries to be as cheap as possible. We don't need
     * to implement the full HTML spec, but rather simply determine where the string
     * looks like an HTML tag, and where it looks like text (so that we can autolink
     * that).
     *
     * This state machine parser is intended just to be a simple but performant
     * parser of HTML for the subset of requirements we have. We simply need to:
     *
     * 1. Determine where HTML tags are
     * 2. Determine the tag name (Autolinker specifically only cares about <a>,
     *    <script>, and <style> tags, so as not to link any text within them)
     *
     * We don't need to:
     *
     * 1. Create a parse tree
     * 2. Auto-close tags with invalid markup
     * 3. etc.
     *
     * The other intention behind this is that we didn't want to add external
     * dependencies on the Autolinker utility which would increase its size. For
     * instance, adding htmlparser2 adds 125kb to the minified output file,
     * increasing its final size from 47kb to 172kb (at the time of writing). It
     * also doesn't work exactly correctly, treating the string "<3 blah blah blah"
     * as an HTML tag.
     *
     * Reference for HTML spec:
     *
     *     https://www.w3.org/TR/html51/syntax.html#sec-tokenization
     *
     * @param {String} html The HTML to parse
     * @param {Object} callbacks
     * @param {Function} callbacks.onOpenTag Callback function to call when an open
     *   tag is parsed. Called with the tagName as its argument.
     * @param {Function} callbacks.onCloseTag Callback function to call when a close
     *   tag is parsed. Called with the tagName as its argument. If a self-closing
     *   tag is found, `onCloseTag` is called immediately after `onOpenTag`.
     * @param {Function} callbacks.onText Callback function to call when text (i.e
     *   not an HTML tag) is parsed. Called with the text (string) as its first
     *   argument, and offset (number) into the string as its second.

    /**
     * @class Autolinker
     * @extends Object
     *
     * Utility class used to process a given string of text, and wrap the matches in
     * the appropriate anchor (&lt;a&gt;) tags to turn them into links.
     *
     * Any of the configuration options may be provided in an Object provided
     * to the Autolinker constructor, which will configure how the {@link #link link()}
     * method will process the links.
     *
     * For example:
     *
     *     var autolinker = new Autolinker( {
     *         newWindow : false,
     *         truncate  : 30
     *     } );
     *
     *     var html = autolinker.link( "Joe went to www.yahoo.com" );
     *     // produces: 'Joe went to <a href="http://www.yahoo.com">yahoo.com</a>'
     *
     *
     * The {@link #static-link static link()} method may also be used to inline
     * options into a single call, which may be more convenient for one-off uses.
     * For example:
     *
     *     var html = Autolinker.link( "Joe went to www.yahoo.com", {
     *         newWindow : false,
     *         truncate  : 30
     *     } );
     *     // produces: 'Joe went to <a href="http://www.yahoo.com">yahoo.com</a>'
     *
     *
     * ## Custom Replacements of Links
     *
     * If the configuration options do not provide enough flexibility, a {@link #replaceFn}
     * may be provided to fully customize the output of Autolinker. This function is
     * called once for each URL/Email/Phone#/Hashtag/Mention (Twitter, Instagram, Soundcloud)
     * match that is encountered.
     *
     * For example:
     *
     *     var input = "...";  // string with URLs, Email Addresses, Phone #s, Hashtags, and Mentions (Twitter, Instagram, Soundcloud)
     *
     *     var linkedText = Autolinker.link( input, {
