Remove all of the documentation.  It didn't really belong in the repo.
(I had thought it would be viewable at github, but it's not.)
Add first version of source code.  (Only the client, still needs lots of
changes.)
Add first simple tests/experiments.  (These require the user to read the
output, so I consider them experiments rather than tests.)
Add top-level Makefile.
Add some information to the README.
