class Recent:
"""
Class used to retrieve recent Trello updates. Uses sarumont's py-trello API wrapper lightly.
Currently I just grab the full lump of data from the board API call.
For my use of Trello this works just fine, but if you're using it really
heavily I could see this using up too much memory, or the resultant xml being too big or something.
Could improve that by specifying exactly what we want with the ?filter param, or digging into using
the lists/cards apis more directly. However, I'm currently serving over 100 rss feeds on
trellorss.appspot.com with this method, so it works well enough, even if it kind of bothers me.
