//	NOTE: In the case where a callback is dynamically attached to an object, the object
//	becomes the 'this' pointer for the method.  Thus several calls to displayState() are
//	referenced using the global object pointer 'cs' rather than the this.  In these
//	specific cases, the 'teuker' object assigns select/unselect methods to the onclick()
//	event handler of dynamically created divs.
