Cpp - Cython - CMake: Initial Commit.

This project demonstrate the integration of Cpp and Cython using CMake.
In its current state it generates a functional Python module that can
be imported and used together with any other Python module.

The idea is to use this setup to provide some Cpp code as the backend
code for a Python webserver, for example web.py or tornado. Let's let
Python handle the front-end part (a problem already solved a million times)
and let's focus our effort in performant code in the backend.

This commit is still a bit rough around the edges.

TODO:

* Comment all the code so that it can be used as a tutorial
* Add tests for the Cpp code
* Add tests for the Python wrappers (nosetest probably)
* Integrate a Python web framewokr (web.py would be my choice)

Added license
Adding more elements.

Cython code integrated in CMake. .so libraries generated
for the Cython + cpp code. Also added tests in the cpp part (not in the python
modules generated).

Added a little web.py application that uses the generated module. The intention
is to show the integration of cpp code into a python web app via Cython.

Still some manual steps, like the installation of the python modules.

The only Python library used is web.py
