Flagging Observations

I spent a few hours creating an API to flag questionable and erroneous observations. It's one of those significant things that needed to happen before the app moves from alpha to beta. Also, in preparation for Yellowstone's season opening, I'm in the process of updating the geyser behavioral models. Everything's happening on the server and database side for now, but I expect to deliver an app update to the Android Market before the end of April. It's also nearing time to open discussions with the community about the nature of the observations' data license. The intent is to make the database open source; it's just a matter of the best approach for that.
