/**
 * @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;
 *         }
 *     } );
 *
 *     // generated html:
 *     //   Test <button title="Load URL: http://google.com">Load URL: google.com</button>
