Copyright notice updated, our first hub application introduced (which is incomplete)
- First application 'test cruncher' for the hub (better say a cloud) introduced.
  This test cruncher shall try to find the right key for an encrypted message.
  It handles all "crunched" keys over work units like dnetc (see
  http://www.distributed.net for instance) does but instead of a central server
  it uses the "hub" as a cloud to store settings and work units in. This is, of
  course, not yet done. More on the wiki: http://wiki.ship-simu.org
