Module engine

A matcher implementation using a simple interpreter-based approach with the Visitor interface. State is encapsulated in State while program flow uses trampolining to avoid exhausting the Python stack. In addition, to further reduce the use of the (non-Python) stack, simple repetition is "run length" compressed (this addresses ".*" matching against long strings, for example).
