/**
 * @class Autolinker
 * @extends Object
 *
 * Utility class used to process a given string of text, and wrap the matches in
 * the appropriate anchor (<a>) 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, {
 *         replaceFn : function( match ) {
 *             console.log( "href = ", match.getAnchorHref() );
 *             console.log( "text = ", match.getAnchorText() );
 *
 *             switch( match.getType() ) {
 *                 case 'url' :
 *                     console.log( "url: ", match.getUrl() );
 *
 *                     if( match.getUrl().indexOf( 'mysite.com' ) === -1 ) {
 *                         var tag = match.buildTag();  // returns an `Autolinker.HtmlTag` instance, which provides mutator methods for easy changes
 *                         tag.setAttr( 'rel', 'nofollow' );
 *                         tag.addClass( 'external-link' );
 *
 *                         return tag;
 *
 *                     } else {
 *                         return true;  // let Autolinker perform its normal anchor tag replacement
 *                     }
 *
 *                 case 'email' :
 *                     var email = match.getEmail();
 *                     console.log( "email: ", email );
 *
 *                     if( email === "my@own.address" ) {
 *                         return false;  // don't auto-link this particular email address; leave as-is
 *                     } else {
 *                         return;  // no return value will have Autolinker perform its normal anchor tag replacement (same as returning `true`)
 *                     }
 *
 *                 case 'phone' :
 *                     var phoneNumber = match.getPhoneNumber();
 *                     console.log( phoneNumber );
 *
 *                     return '<a href="http://newplace.to.link.phone.numbers.to/">' + phoneNumber + '</a>';
 *
 *                 case 'hashtag' :
 *                     var hashtag = match.getHashtag();
 *                     console.log( hashtag );
 *
 *                     return '<a href="http://newplace.to.link.hashtag.handles.to/">' + hashtag + '</a>';
 *
 *                 case 'mention' :
 *                     var mention = match.getMention();
 *                     console.log( mention );
 *
 *                     return '<a href="http://newplace.to.link.mention.to/">' + mention + '</a>';
 *             }
 *         }
 *     } );
 *
 *
 * The function may return the following values:
 *
 * - `true` (Boolean): Allow Autolinker to replace the match as it normally
 *   would.
 * - `false` (Boolean): Do not replace the current match at all - leave as-is.
 * - Any String: If a string is returned from the function, the string will be
 *   used directly as the replacement HTML for the match.
 * - An {@link Autolinker.HtmlTag} instance, which can be used to build/modify
 *   an HTML tag before writing out its HTML text.

         *
         *     truncate: { length: 25, location: 'middle' }
         *
         * @cfg {Number} [truncate.length=0] How many characters to allow before

         * @cfg {"end"/"middle"/"smart"} [truncate.location="end"]
         *
         * - 'end' (default): will truncate up to the number of characters, and then
         *   add an ellipsis at the end. Ex: 'yahoo.com/some/long/pat..'
         * - 'middle': will truncate and add the ellipsis in the middle. Ex:
         *   'yahoo.com/s..th/to/a/file'
         * - 'smart': for URLs where the algorithm attempts to strip out unnecessary
         *   parts first (such as the 'www.', then URL scheme, hash, etc.),
         *   attempting to make the URL human-readable before looking for a good
