[erlang-questions] [ANN] eunit_formatters

Let's face it, the output from eunit is pretty awful, even with the
'verbose' flag on. It's not made for average humans. I got fed up and
created a new tool to ease my pain:

Its main features are:

* Prints progress through the test suite on a single line as dots (Pass),
asterisks (Skipped), and 'F' (Failure/exception).
* At the end of the suite:
  * Prints skipped tests and groups
  * Prints test failures; built-in eunit assertions have more
human-friendly text
  * Prints the top 10 slowest tests (as determined by wall-clock time)
  * Summarizes the time elapsed and the success or failure status
* Optionally prints output in color via ANSI-escape sequences

Instructions for how to set it up with a rebar-based project are included
in the README.

Those of you who have used the RSpec runner in Ruby will recognize the
formatting, I basically mimiced it.

There's lots still to do here, but I hope people can try this on their
projects, start tinkering with the code, and help me improve it.
Pull-requests are encouraged.
