* Merged mongo_btree, mongo_conn, mongo_lock, mongo_mem and mongo_ops…
… into single script and removed header files.
* Read both host and port of MongoDB from environment variables. I think this is the munin way.
Always use `/usr/bin/env python` in shebang line
Possible to specify host in Munin config
# cat /etc/munin/plugin-conf.d/mongo
make everything 0 based CASE 1
conn and lock tests
better build script
generate so can re-use code
mem info and fixes
