/*
@description Bind mouse click and enter key to a given element. On Click or Enter, specified function is called and default event action blocked.

Sample use is to add popup to a link, where the href would be followed if javascript were turned off.


var popup = function() {
	alert('activated');	
};
$(document).ready(function() {
	$.clickOrEnter('a',popup);
});


var popupKnowing = function(thing) {
	thing.style.display = '';
	alert('shown');
}
$(document).ready(function() {
	$.clickOrEnterWithElem('a',popupKnowing);
});
