/**
 * @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 (map) 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#/Twitter Handle/Hashtag match that is
 * encountered.
 *
 * For example:
 *
 *     var input = "...";  // string with URLs, Email Addresses, Phone #s, Twitter Handles, and Hashtags
 *
 *     var linkedText = Autolinker.link( input, {
 *         replaceFn : function( autolinker, 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 = autolinker.getTagBuilder().build( match );  // 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 'twitter' :
 *                     var twitterHandle = match.getTwitterHandle();
 *                     console.log( twitterHandle );
 *
 *                     return '<a href="http://newplace.to.link.twitter.handles.to/">' + twitterHandle + '</a>';
 *
 *                 case 'hashtag' :
 *                     var hashtag = match.getHashtag();
 *                     console.log( hashtag );
 *
 *                     return '<a href="http://newplace.to.link.hashtag.handles.to/">' + hashtag + '</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.

	 * characters, it will be truncated to this length by adding a two period
	 * ellipsis ('..') to the end of the string.
	 *
	 * For example: A url like 'http://www.yahoo.com/some/long/path/to/a/file'
	 * truncated to 25 characters might look something like this:
	 * 'yahoo.com/some/long/pat..'
	 *
	 * Example Usage:
	 *
	 *     truncate: 25
	 *
	 *
	 *  Defaults to `0` for "no truncation."
	 *
	 *
	 * ## Object Form
	 *
	 * An Object may also be provided with two properties: `length` (Number) and
	 * `location` (String). `location` may be one of the following: 'end'
	 * (default), 'middle', or 'smart'.
	 *
	 * Example Usage:
	 *
	 *     truncate: { length: 25, location: 'middle' }
	 *
	 * @cfg {Number} [truncate.length=0] How many characters to allow before
	 *   truncation will occur. Defaults to `0` for "no truncation."
	 * @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
	 *   point to insert the ellipsis if it is still too long. Ex:
	 *   'yahoo.com/some..to/a/file'. For more details, see
	 *   {@link Autolinker.truncate.TruncateSmart}.

	 * url/email/phone/twitter/hashtag links differently.
	 *
	 * For example, if this config is provided as "myLink", then:
	 *
	 * - URL links will have the CSS classes: "myLink myLink-url"
	 * - Email links will have the CSS classes: "myLink myLink-email", and

/**
 * @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( autolinker, match ) {
 *             var tag = match.buildTag();  // returns an {@link Autolinker.HtmlTag} instance, configured with the Match's href and anchor text

 *
 *     // 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( autolinker, match ) {
 *             var tag = new Autolinker.HtmlTag( {
