Instrumentation - Simple instrumentation framework inspired by ActiveSupport::Notifications

This is basically a port of ActiveSupport::Notifications.

Cream (a Dalli compatible memcached client) uses it now.

As always, fully documented. Check it out, it’s really simple and easy to use…

I would really like to see people start using this for their various libs, and then packages like instrumentation-statsd, instrumentation-logger, instrumentation-datadog, etc start popping up.
