/**
*	Tallest.
*	Given a jQuery result set, this set of functions will return the:
*	- tallest()		(biggest height)
*	- shortest()	(smallest height)
*	- widest()		(biggest width)
*	- thinnest()	(smallest width)
*	Add "Size" onto the end of those functions (eg: "tallestSize()") and it will
*	return just the pixel size, not the element.
