Feature Request: output solutions and commentary to .md file

[marrowb]

I am a programming newbie so maybe this request is way too complex, but I think it would complement exercism's philosophy if there was an easy way to concatenate the iterations and commentary into a file for the student's purposes. This way, if the student has been reflecting on their solutions/what they learned, they can organize all that information into a file and use it in the future as a sort of cheat sheet. Once again, I am not really familiar with how difficult it would be to implement this feature, I just know that it would be super helpful to have this kind of compendium of what the student has learned in one place.
