What's this PR do?

• Move logic for determining incoming collisions into collision engine class.
• Gave collision engine an object instance instead of binding one on method calls
• CollisionEngine now calculates all possible colliders with its object, and returns a boolean on whether the player/fire-block/bomb can occupy the corresponding space.
• Topic of refactor focused around Law of Demeter. However by moving the logic off of the player class and into the CollisionEngine class - it appears that CollisionEngine is doing a lot of logic for a lot of different scenarios. Also attempted to break functions out into objects similar to the way the lesson had suggested (colliisionEngine - lines 6-24) - but unsure of what practical value it provides.

Where should the reviewer start?

• Scroll ALL the way to the bottom and check out the code that had initially been on the player class and compare to the new function in its place.
• Then checkout the other places in which the CollisionEngine methods are being called.
• Checkout the CollisionEngine class (specifically lines 6-24)
