Restructure project to work as an Elm package

[ohanhi]

First off, I am sorry for the hugely noisy diffs in this branch. This is some pretty fundamental restructuring for the whole project, however, so noise is inevitable in that sense.

What I've done so far:

• Moved all relevant package files to ./src
• Moved usage example files to ./examples
• Removed android and ios directories altogether
• Renamed a bunch of stuff to be more intuitive for the end user

I also forked the compiler and core, but haven't yet updated them. My idea was that while we are in this phase of "DIY", it makes sense for the compiler and core modifications to be a part of the same project.

What purpose do the android and ios folders have anyway? Where do they fit in? do they need to be part of core?

@eeue56 No, they are generated by React Native when you start a project with react-native init MyProject. So it was always a little strange to have them in this repository.
