Refactoring

[rdelaage]

Hi, I was trying to implement #256 and was thinking that it could be a good idea to make some refactoring to the code base to maintain it more easily. Especially it could be a good idea to create some modules like config to handle all configuration thing or a logger module, add some generic functions were necessary, ...

Do you think it is a good idea ? I would be happy to work on this :)
