[PATCH 2/3] A simple python script to parse the results from the testcases

[Sverre Rabbelier <srabbelier@gmail.com>]

This is a simple script that aggregates key:value pairs in a file.
I am sure this can be done better with a 'grep | sed | awk' combination,
my skills with awk / your program of choice is not as profound.
This script serves more as a demonstration on how to use the testcase output.
