[OpenLayers-Users] Removing popups with clicks on map

[Erik Uzureau]

If you only want to be displaying one popup at a time, it probably
wouldn't kill grandma to just make a global variable... like
OpenLayers.map.MyPopup or something like that. Then you can kill
it from anywhere without worrying about passing the reference.

If you want to allow multiple popups at once, however, you will
need a more complex system.
