/**
	Hover Accordion Menu
	A jQuery menu accordion plugin that works on roll over instead of the 
	typical mouse click accordion. What sets this plugin appart is that it 
	automatically retrieves back on mouse leave. 
	
	Hover Accordion Menu uses Brian's Hover Intent to determine the best
	mouse over and mouse out produced by the user.
	
	Further features will be added in future realeases, including, option to 
	change from on mouseover/mouseout to on mouseclick, and other options.
