parseImageSets

A function used to split a comma separated list of image sets into an array for reference to the viewer and json calls

output:  none, this function writes to a globally defined object imagset_test

initializeJSON

A function used to make the initial calls to load imageset properties via JSON from the image server and perform the necessary steps to parse that data into useful objects for reference by the page

input:  string of comma separated Image Sets
output:  None
usage notes:  In this code the initializeJSON method should be called when declaring the image argument that will be passed to the viewer
				  the function will return a comma separated list of company/imagesets that can then be passed to the viewer, and will as side
				  effect perform the other necessary actions in order to initialize the page with JSON support
