SAT collision for haxe

[underscorediscovery]

Hello haxe group, 

A while back, I created a direct port of this code, and submitted it to the haxelib repo as "hxcollision".
Today I had a few minutes and updated it to include bug fixes, and new features (like ray/line collision tests).

I figured I will post it here for others to use, here are the facts:

• This is a port of Separating Axis Theorem, for collision detection between shapes, and lines.
• Supports polygons and circles, and line/raycast collisions currently.
• See tests/ for a OpenFL ready test project. Also includes OpenFL drawing class. 
• The library itself is not specific to OpenFL. 
  
• COLLISION ONLY. No physics here. By design :)
• Contributions/bugs/requests welcome

There is a live demo here : Flash demo

Github repo : https://github.com/underscorediscovery/hxcollision/
Haxelib repo : `haxelib install hxcollision` or http://lib.haxe.org/p/hxcollision

Other notes : 
 - This was a direct port, a lot of the code is a bit untidy and definitely needs cleanup. I plan to do this in the near future.
 - The library appears to be stable with rotated polygons and all that, just be aware of "order of operation" between translation, scale and rotation. Rotating after a translate will rotate around the origin still.

 - Create issues on the github page for bugs, or features etc.

 - Tested in flash, android, iOS, mac, html5 

Enjoy, and I look forward to seeing what you use it for!
