Profile comparison functionality

Didn't see this in the stickied thread/ruled out items.

It would be nice if, while viewing another players profile, you could tap a "Compare" button and have a side-by-side comparison of your progress against the viewed player (this would include the troop level portion as well as the achievement portion). Perhaps even a graphical red/green bar graph to show who is further along than whom for a specific item/subject. For achievements that are maxed out (gold grab, etc), show current values as in the full profile with the graph being maxed out at the person with the highest value.
