Litreview

Add a literature review directory with our rudimentary bibliography and a list of papers we have not yet acquired. Our top priority should be to get this bibliography into a state of being a correct BibTeX file. That may mean moving the annotations somewhere else, which would be totally fine. Perhaps we should give each paper we read in-depth (such as Beth14) its own LaTeX file (which we can then \input in our actual bibliography). In that case, papers we merely skimmed could possibly have a comment field in their bibliography entry.

I have a legally-obtained archive of most of the papers for which there are real citations; for legal and technical reasons I will not upload them here, but I will send you an archive with what I have. Simply unzip them in your "literature" directory, and we will be in sync (and I updated the .gitignore to ignore them as well). The papers I had trouble acquiring are listed in the "missing_papers" directory.
