Mongo Rails 3 Instrumentation

Records how long your rails app spends in Mongo, and outputs it to the log, i.e.:

Completed 200 OK in 1535ms (Views: 623.3ms | Mongo: 848.2ms)

To use, just add the gem to your Gemfile and restart your app:

gem 'mongo-rails-instrumentation', '~>0.2'

It's been tested with rails 3.0, and should work with rails 3.1 too.
