/**
	PerspectiveUIFrame is a javascript class that represents a set of UI windows forming an 
	application "view" much like an Eclipse perspective.  
	
	The UI windows are defined in a spreadsheet named range from which window layout and source
	urls are determined.
	
	The spreadsheet namedrange is accessed through the RESTful Spreadsheet Server API and returned
	as a JSON javascript array.
	
	JavaScript Windowing is then used to instantiate the window layout.
		
	...
	 loadUI -- loads the windows based on named range values
	 
	 "http://127.0.0.1:8080/workbook/id/1301/csv/namedrange/getcellvalues/windows/0" returns:
	 'crm','/uimodules/crm/intro.jsp','true','?daterange=1+2','10','50','300','400','open CRM','invoice template','/uimodules/crm/intro.jsp','true','?daterange=1+2','20','30','150','250','open last viewed invoice'
	 this is one window definition:
	 'crm','/uimodules/crm/intro.jsp','true','?daterange=1+2','10','50','300','400'
