Towards a complete rewrite...

Implemented a new Client class. The new implementation directly accesses the
Twitter REST API v1.1 without additional library dependencies.
Authentication is done using the "application only" option.

renamed twitter_graph_gen.py to create_net.py

This is version is only capable of authenticating the application and getting
the connection token

The configuration file fields are reduced to the essentials: consumer_key and
consumer_secret
Merge branch 'master' of github.com:mariosv/twitter-followers
