// jquery.event.hover.js - rev 5 
// PLUS Modification made by Andy Ballingall May 2 2010 to continue the hover state if
// the mouse only transiently moves off the hover element.
// On mouseout, the hover isn't cancelled immediately, but only after a timeout. (Set to the 
// same delay as for the speed evaluation mechanism)
// If the mouse reenters the hover area again before the expiry of this timeout, then the 
// hover continues as if the mouse had never left. Only if the mouse remains outside the
// area for long enough does the hover complete.
// ABHERE - need to share this underneath.
