Added cython into the mix.

C++ is brilliant for IO level programming. But kinda of gets tedious to code higher level
distributed systems at least as a one man team. There is not point in writing code that
doesn't scale linearly with VM based languages. cython gives a middle ground where we can
link python with C.

Basic wiring of pyx into the code and addition of simple wrappers to enable access via cython.
