Include screenshot in readme showing what it do

If I come here from Google/whatever/ how do I know what it is and how it differ from others?

Other packages with similar functionality e.g. https://github.com/neubloc/django-colortools https://pypi.python.org/pypi/pyrg https://pypi.python.org/pypi/rudolf/

Good idea.

For the record:

• django-colortools does not tie in nicely with django's discover runner, and seems to be unmaintained.
• pyrg does not support python 3
• rudolf is for nose tests, not unittest tests.
