Each record will be uniquely identified based on:
(tagname, user_id)
tagnameis user specified when lightlog data is uploaded.user_idis the integer of the user in the user database.
Right now we'll be allowing multiple entries for a given tagname and user_id
Because of this, queries should pull only the most recent entry. As part of application queries you should append:
{"sort":[("timestamp",-1)],"limit":1}
All data is in the geologger database in mongodb.
