From a71c65a45586b3f6cd5032016621d41d62a8c4f0 Mon Sep 17 00:00:00 2001 From: Dmitri Pal Date: Mon, 14 Sep 2009 12:52:23 -0400 Subject: COLLECTION Adding item comparison and sorting Needed item comparison functions and realized that the easiest way to test them would be using sorting. Since there already been a ticket #73 to do that I added function to sort collection based on different properties of the item.
