	runs once the DOM is ready, rather than waiting for the entire page to load. 
	As a result it runs earlier as it doesn't need wait for images/flash to load.

	Changed way that onReady() is passed to DomReady() - passed call to function rather than the function, this allows me to change onReady using addDomEvent (below)
