/* Parse function for JavaScript. Makes use of the tokenizer from
 * tokenizecsharp.js. Note that your parsers do not have to be
 * this complicated -- if you don't want to recognize local variables,
 * in many languages it is enough to just look for braces, semicolons,
 * parentheses, etc, and know when you are inside a string or comment.
 *
 * See manual.html for more info about the parser interface.
