Subject: Restructuring the main API and project

This commit rewrites pretty much the entire library. It is now much
smaller and more maintainable (split over multiple files). It will now
also support more features (that aren't implemented yet).

Adding two examples to show how to use the new API. Also changing the
name of the library everywhere.
