Please add Collection/Folder Stats page

[Codebot2455]

Can you please add the Collection/Folder Stats source code from http://labelme2.csail.mit.edu/Release3.0/index.php

I would really like to have a leaderboard/stats on my collections or folders. I'm willing to help merge this feature from the website to the public github sourcecode.

see also #61 , I'm not sure if your suggestion covers this but it would be nice to see the total you have added accumulated somewhere (not just viewable as part of the collection)
