' DESCRIPTION:
'   Scripts for Google maps
' UPDATES
'   2010-11-18 Ola Ljungars: fixed bug with CheckOverRides()
'   2010-11-18 Ola Ljungars: Added the markerClick function again for fc override
'   2010-10-25 Ola Ljungars: API 3.0 Version
' TODO
'   - Add a class for print markers (css also), hide them when screen
'   <style type="text/css">
'			@media print{.gmnoprint{display:none}}
'			@media screen{.gmnoscreen{display:none}}
'		</style>
'
'   - Update the markers when zooming / panning only in Firefox, IE hand handle
'			this either by fixing the style opacity or by adding the icon onbefore print
