PyPTV 0.1.1

This version compiles against liboptv, Python bindings and passes all the tests: C code is tested using Check unit testing framework, Cython/Python bindings and PyPTV are tested separately and altogether using nosetests, on Travis-CI

PyPTV is a Python based GUI for OpenPTV library

This is our first release that does not use C code except the @OpenPTV liboptv library and Python bindings.
