// General Library object. This section defines an object so that we can
//	a) Create a fake namesapce so that variables don't conflict with other scripts
//	b) House properties and functions that will be general to a number of different classes
//	c) Put in a shameless plug for me.

//Defines the object in which we can collect all a bunch of properties and functions
//that our universal to our library (which, at present consists in its entirety
//of one tooltip class).
