Provides aspects for use with Morphe (https://github.com/Workiva/morphe)

This is a pretty thin wrapper of Coda Hale
(https://metrics.dropwizard.io).  Unlike the metrics-clojure library
(https://github.com/metrics-clojure/metrics-clojure), this doesn't
destroy your ability to program to interfaces common to the
different kinds of metrics.

The one major constraint this wrapper adds is that you must supply a
docstring when you create metrics. Do it. Don't cheat. We don't need
anonymous mysterious metrics out there. If it's worth recording,
it's worth saying what it is!!

On that note, you can get explanations for each metric with
(explanation) and (explain).
