v0.1.4 - Unit tests

Hi there, everybody.

This is the first version of this lib with unit tests that cover almost 100% of the codebase. There is some very minimal stuff missing and I kept one failing test to remind me that I still need to add some last tests for the internal caching mechanism. It will probably be available in the next release (I hope to get 100% until there).

Also, the next release is planned to have more ways of magical identification rather than just the path and, if the time allows it, have a better Readme with the new methods and changes.
