 //   Function:      adds javascript events to elements that simulate CSS actions that some older browsers do not support.
 //			  		 loadLocationMaps, mapLocationOn and mapLocationOff are all inter-related.
 //   Inputs:        none
 //   Returns:       n/a
 //   Author:        James Offer
 //   Usage example: use in onload on body - will automatically add javascript events to all required elements
