CursorModule

-- Module to replace the built in MouseEnter and MouseLeave functions with a position argument. Which I wasted 3 hours on because last time I used the built in functions it was extremely reliable than when I finished this I decided to test the built in functions for the first time in 2 yrs js to found out it was way way more reliable now so I decided to put my custom one and the built in one side by side and mine was like 1% more reliable on computer so no difference basically.
