Built main structure and filled methods

[JoaoCarabetta]

Here I built the basic structure of the Python Client with two examples to Camara dos Deputados

It closes issue #25, #2, #3, #4, #5, #6, #7

However, I did not implemented tests!

The code is ready to use by installing

python3 setup.py install

and then run a python code with

import cn_api_client
camara = cn.Camara()
camara.deputados.obter_detalhes_deputado(141428)
camara.deputados.obter_deputados()
