created the empty shells of the player class and enemy class
added thisx, thisy, thisvel
added a destructor and some conditions to check if enemy has been garbage collecter to engine.js
this will go away
added generator methods for velocity, x and y coords
added the shell of player methods
working on the collision boxes for enemies
refactored class prototypes to on object instead of multiple individual objects
collision, more collisions, and messy, going to refactor intersect to accept rect objects instead of arrays
refactored collisionBox to be a Rect object
collisions working mostly properly
