Synopsis - Issue Tracker

When parsing a python file, the parser strips of 
the base path, and assumes for the remainder it 
represents a set of nested packages 
('AST.Module').

Test that this is indeed the case (check for the
existence of local '__init__.py' files), and if
not, print out a useful error message.

The new Python parser raises meaningful exceptions
now.
