/**
* @class Autolinker
* @extends Object
*
* Utility class used to process a given string of text, and wrap the URLs, email addresses, and Twitter handles in
* the appropriate anchor (<a>) 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 yahoo.com'
*
*
* 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 yahoo.com'
*
*
* ## 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/Twitter handle match that is encountered.
*
* For example:
*
* var input = "..."; // string with URLs, Email Addresses, and Twitter Handles
*
* 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 'twitter' :
* var twitterHandle = match.getTwitterHandle();
* console.log( twitterHandle );
*
* return '' + twitterHandle + '';
* }
* }
* } );
*
*
* 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.

* @class Autolinker.HtmlTag
* @extends Object
*

*
* 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'

*
* // 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.toString(); // Google
*
*
* ## Example use within a {@link Autolinker#replaceFn replaceFn}
*
* var html = Autolinker.link( "Test google.com", {

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