class Tokenizer

This class takes a set of highlighting rules, and creates a tokenizer out of them. For more information, see [the wiki on extending highlighters](https://github.com/ajaxorg/ace/wiki/Creating-or-Extending-an-Edit-Mode#wiki-extendingTheHighlighter).

 
new Tokenizer(rules, flag)
- rules (Object): The highlighting rules
- flag (String): Any additional regular expression flags to pass (like "i" for case insensitive)

Constructs a new tokenizer based on the given rules and flags.
