Description: Contains functions needed to help properly generate a webpage 
             containing an embedded PCS IFrame.
             
             Expected usage: 
                In code that generates IFrame, use EmbeddedPcs.generateURL() to create value for 'src' attribute. 
                  eg: document.writeln("<iframe name='pcspro' src='" + EmbeddedPcs.generateURL() + "' width='750' height='400' frameborder='0'></iframe>");
