/**********************************************************
Function:
getElementsByClassName

Purpose:
Provides compatibility for getElementsByClassName (a native function in
many browsers) for browsers that don't support it (IE).

Input:
className -  Mandatory. One or several class names, separated by space. 
Multiple class names demands that each match have all of the classes 
specified.
tag - Optional. Specifies the tag name of the elements to match.
elm - Optional. Reference to a DOM element to look amongst its children for
matches. Recommended for better performance in larger documents. 
            
Output:
An array of elements

Assumptions:
-

Examples:
To get all elements in the document with a “info-links” class.
getElementsByClassName("info-links");
    
To get all div elements within the element named “container”, with a “col” class.
getElementsByClassName("col", "div", document.getElementById("container")); 
    
To get all elements within in the document with a “click-me” and a “sure-thang” class.
getElementsByClassName("click-me sure-thang");
