A program to make fermi problems eaiser and more vivid

Make sure you have the Canopy virtualenv sourced (otherwise GUI toolkits won't be found). I.e. install Canopy, and then to be sure you are in that venv:

source /Users/<home>/Library/Enthought/Canopy_64bit/User/bin/activate

Make sure you have qt4 set as the default toolkit:

`export ETS_TOOLKIT=qt4`

Once cloned, just run python fermi_script.py from top directory
