OP2/PyOP2 — pull request #41 by dham (2012-08-16 13:59:18+00:00)
Title: Class heirarchy refactorisation.

Refactor the code so that classes are declared in base.py, although without any assumption that runtime data is available at that stage.

Classes which need runtime data are subclassed in runtime_base.py.
op2.py and all the backends now import their classes from base and runtime_base rather than from sequential.
