Switching Input Method

In the interests of testing, standardizing input, and improving ease of use my next work item is to transition Scaffold from taking in plaintext files as input to taking the urls of articles as input.

This was originally intended to be an improvement implemented after the v1 webapp is up and running, but I'm pushing it ahead. The more I think about it, the more I realize there was no sane world in which I manually collected, copied, pruned, and stored all of the testing documents. I will keep the option to read input from a pre-existing plaintext file as well, though.

I merged the verbosely named "Development_to_Overcome_Errors_Found_During_Testing" branch back into Master after cleaning up the first round of parsing errors. I'm going to close down that branch and make a new one dedicated to transitioning the input method.
