	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"]);
