tool for creating parson's problems

[raynamharris]

On of our instructor's in training, @pllim, developed a really cool python script for creating parson's problems. You input a few lines of python code, and the output is a scrambled block of code with the indentation removed. This could be a really nice thing to use for creating challenges!
