Name change in the C/Python/Octave API

Classes for embedding Python and Octave are now included inside the TinkerCellCore library.

Names of the base classes have changed to avoid confusion with the existing Octave classes. All data structures now have a tc_ prefix to avoid collisions. Here is the detailed documentation:

All the function names available in the link above can be called from C, Python, or Octave.
