/*
	Overview:	PipView is a JS object that controls the images and viewing
		of a PIP
	Usage:	An instance of this object needs to be instantiated on each
		pip page. The markup should be structured so that the main
		image has an id of "pip-main-image" and the thumbnails should
		be inside the pip-thumbs div. Each thumbnail should have a
		class name of pip-thumb and be wrapped with a link that has
		a class of thumb-control. The link should point to the large
		image URL for accessibility and parsing.
		NOTE:
		* The thumbnail anchors must have a class name of thumb-control
		* The path to the large images should be the href of the links
	Arguments:	NONE
	Methods:	Object is self-initializing so the constructor is built in.
			toggleImage: 	Switches the src for the main image
	Sample Use: var myPipViewer = new PipView();
