 *  for a complete explanation.
 *
 *  This extension already exists in some browsers (namely, Firefox 3), but
 *  we provide it to support those that don't.
 *
 *  Parameters:
 *    (Object) obj - The object that will become 'this' in the bound function.
 *    (Object) argN - An option argument that will be prepended to the 
 *      arguments given for the function call
