Some primitive Well support, and the needed classes to get a well from a
deck.
In an effort to reduce boilerplate, the delegate decorator is
introduced. Delegated classes from sunbeam.py can wrap around the python
classes generated by boost and augment their interface, but leverage the
original C++-object as its storage. Methods defined on the immediate
python objects bubble up.
Adds the pycmake makefile dependency and provides a submodule for build
convenience. Adds the SPE3CASE1 test case for some simple test writing
and a test template file.
Sets up python library structure.
