Title: Make Cython optional.  Use *.c files when deployed.

Addresses #4. Cython is optional. When deployed, Cython is never used by default.

Cython is used by default to build *.c files for developmental versions.
TravisCI tests were added to verify building works without Cython.

I'll write more about this on Friday.
