[OSM-dev] Using changesets-latest.osm

[Toby Murray]

I present ChangesetMD:

As noted in the readme, this is my first real python so I can't
guarantee it won't try to erase your hard drive although this seems
kind  of unlikely :)

Right now I have indexes on tag key/values and user name. Depending on
what you are querying on, others might be called for. I'll see what
happens when I start playing with the data.
