/**
* @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>
