A set of utility functions used to reproduce the effect of elastic collision within HTML5 canvas. Used in the Chris Courses tutorial video on collision detection: https://www.youtube.com/watch?v=789weryntzM

* Check if 2 circles collide
*
* Takes velocities and alters them as if the coordinate system they're on was rotated
*
* @param Number | p1x | x coordinate of the first particle
* @param Number | p1y | y coordinate of the first particle
* @param Number | r1 | radius of the first particle
* @param Number | p2x | x coordinate of the second particle
* @param Number | p2y | y coordinate of the second particle
