The conf.py configuration file for Sphinx-doc and setup.py configuration file for setuptools now fetch current package version directly from package. This means, that from this point forward it is necessary to change version number only on one place, the package __init__ file.

* Greatly improved module documentation
* Code style improvements with the use of pylint tool
* BC breaking refactoring to unify code style
* Multiple minor bugfixes

Note: I am well aware of the ugliness of such a huge commit. However all of the changes were done in a short time and as part of a single big feature upgrade and in my opinion in this case I can justify that, because all changes are related to one another.
