fixed communication bug, for void return filesystem calls fs returned {ok} and client expected {ok,Result}. Also added a test to testfs.erl, added debug messages to client, fs, and server.
simple no-argument run scripts for 3 node phat that tear down a previous run, including deleting logs, then compile the code and run phat, either with a client set up to talk to phat or not.
adding some crap to gitignore
