// popup.js 
// expects :
//			url - of the window to be called
//			Title -  for the window, each unique title spawns a new window
//			width - in pixels of the desired window
//			height - in pixels of the desired window
//	hence a legal call would look like:
// <a href="JavaScript:popWindow('myurl.htm','popupwindowname','520','615')" >click here to spawn window</a>
