Collision Detection : Broad Phase algorithm

[aesee]

Added simple algorithm of 2D Collision Detection and made test for it.
My first experience with open source, i'm sorry if something wrong.

I'm working on a geometry library as well, with some minor merge commits as this one (specifically __init__.py). Currently just got the specs for it (http://pygorithm-fork.readthedocs.io/en/latest/Geometry.html) but it wouldn't hurt to take some precautionary measures:

I think you should consider renaming the file to broad_phase.py or rect_broad_phase.py to be more specific, and rename Body to Rect, SimpleRect, Rectangle, or something of that sort. Body is typically more general than a rectangle.

As you might know, broad-phase collision detection typically requires some sort of grid for it to have practical application. I was considering making a quad-tree, but a spatial tree or R-tree would work as well.

EDIT: Don't take anything I say too seriously until OmkarPathak gets a chance to look at it 👍

Thanks for the comment!
I renamed file and class to proposed and made a new commit. It wasn't hard.
I think I can write another implementation of broad phase for quad-tree if it is needed.
