* @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(); // 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.toAnchorString(); // Google
*
*
* ## 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 google.com
*
*
* ## 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() },

/**
* Parses an HTML string, calling the callbacks to notify of tags and text.
*
* ## History
*
* This file previously used a regular expression to find html tags in the input
* text. Unfortunately, we ran into a bunch of catastrophic backtracking issues
* with certain input text, causing Autolinker to either hang or just take a
* really long time to parse the string.
*
* The current code is intended to be a O(n) algorithm that walks through
* the string in one pass, and tries to be as cheap as possible. We don't need
* to implement the full HTML spec, but rather simply determine where the string
* looks like an HTML tag, and where it looks like text (so that we can autolink
* that).
*
* This state machine parser is intended just to be a simple but performant
* parser of HTML for the subset of requirements we have. We simply need to:
*
* 1. Determine where HTML tags are
* 2. Determine the tag name (Autolinker specifically only cares about ,
