	Ways of calling the function now are:

	To get all a elements in the document with a “info-links" class.
	getElementsByClassName(document, "a", "info-links");
	
	To get all div elements within the element named “container", with a “col" and a “left" class.
	getElementsByClassName(document.getElementById("container"), "div", ["col", "left"]); 

	Note that you can still use a string when only looking for a single class name, but an array when
	looking for multiple class names.
