/**
 * Splits a chunk of HTML into 'text' and 'tag' tokens, for easy processing. Is VERY tolerant to badly formed HTML.
 * <p/>
 * <h3>Usage</h3>
 * <p/>
 * You need to supply a custom {@link TokenHandler} that will receive callbacks as text and tags are processed.
 * <p/>
 * <pre>char[] input = ...;
 * HTMLTagTokenizer tokenizer = new HTMLTagTokenizer(input);
 * TokenHandler handler = new MyTokenHandler();
 * tokenizer.start(handler);</pre>
