I have been working on polishing Knute's code. Mostly I have been
adding informal comments and renaming to help myself understand how it
works.

I have not run it yet, but it is getting close to a test.

see
https://wush.net/svn/mindprod/com/mindprod/singleinstance/SingleInstance.java

I have added UUIDs to break the tie for equal start times.
I have added app ids so different apps can share the same port.

I have added the ability avoid several different apps.
I have added the ability to permit two apps to run, so long as they
run on different files.
