PyOpal - build system
Build system and a couple of simple examples for opal<->python API
I would like to merge in my current working tree, by way of debugging all of the build system stuff for pyopal. At the moment I have working code that will allow users to link against python and build C/python libraries. I have implemented a couple of examples:
- Access to a few polynomial routines
- Access to the OpalRing for field lookups
Obviously not full implementation of #516 but an opportunity to get a bit of feedback on the interface for building libraries/etc.
