Ann: Plex 1.1 - Lexical Analysis - Case insensitivity

[Greg Ewing]

I've added Case() and NoCase() constructors for
controlling case-sensitivity.

Abstract:

Plex is a Python module for constructing lexical analysers, or
scanners. Plex scanners have almost all the capabilities of the
scanners generated by GNU Flex, and are specified in a very similar
way. Tokens are defined by regular expressions, and each token has
an associated action, which may be to return a literal value, or to call
an arbitrary function.
