-
- Specifies a pattern to match, the type of token it represents, what mode the
- token changes to, and what mode the token applies to.
-
- Modes allow more advanced grammars to be incorporated, and are also necessary
- to tokenize line by line. We can have different patterns apply to different
- modes - i.e. looking for documentation while in comment mode.

- regex: The regular expression representing this matcher.
