This script simulates the interaction of celestial objects in an n-body system.
	
Requirements:
	VPython visual library
		Download at: http://vpython.org/
		
Working Components:
	Gravitation between multiple objects
	Collisions
	Trail mapping
	Color changing
	Trajectory reversal
	Pause/Play functionality
	Material switching
	Add/Subtract celestial bodies
	Add/Subtract massive meteors
	Drag and Drop celestial objects
	Camera centers on star
	Addition of multiple stars
	
Execution:
	Run the script and use the commands detailed in the console window
	
Controls:
	a: add planet
	s: remove the last added object, does not remove star
	k: add meteor, incredibly massive, can knock star out of place
	r: reverse the orbits of the planets
	t: toggle whether trails are shown or not
	p: pause/play the simulation
	m: toggle whether or not objects use textures
	c: enable or change solid color appearance of objects
	b: add star to system
	You can also click on objects to reposition them, click again to release
	The object retains its velocity
