/*
This can be used on any element you wish to change CSS classes.
I've left the elementName in the argument in case you want to affect something other than itself.
elementName and event are appended to create the className you are shifting to so make sure your CSS classes are named appropriately.
For example: elementName="TDheader" and event="over" className must equal "TDheaderover"
