Reassembling the polygonal library

I’ve just finished restructuring my library into smaller parts – this was necessary because the previous monolithic approach has become really hard to maintain. Now, I can push updates more frequently and adding new stuff should be also much easier.
The various parts of the library are now hosted on github:
I apologize for any inconvenience and hope the reorganization does not break that much code.
BTW, the library now fully supports Haxe 2.10 :)
