satJS

A simple JS module for checking for collisions between two shapes using the Separating Axis Theorem
*** ONLY WORKS FOR CONVEX SHAPES ***

USAGE

Create two shapes using Vec2 for the vertices
e.g.

const shapeA = new Shape([new Vec2(0,0), new Vec2(2,0), new Vec2(1,1)]);  
const shapeB = new Shape([new Vec2(10,10), new Vec2(20,10), new Vec2(15,20)]);

Use satModule's init function with the two shapes as arguments to check it the shapes are colliding and if they are, to return the Minimum Translation Vector (i.e. the penetration depth and the collision norm)
e.g.
```
const ab = satModule.init(shapeA, shapeB);  
ab.collision     ----> returns false  
ab.penetation    ----> returns 0  
ab.norm          ----> returns (0, 0) [Vec2 object]  
```
