How to expose the functionality of external libraries

[p1gp1g]

There are basically 2 ways to do that:

• Exposing the dependency directly as an api dependency, and using the dependency's classes for internal process (like passing extra data for intents)
• Write new classes/wrapper that call the library

The former makes it easier to take advantage of new features, while the latter improves control over updates.

Note: the question has been raised for #3. I've used the first option, at least in a first time
