* discussed and added plt data plan
  * discussed and modified bhm data plan, reducing data size by half
  * notes on running examples on brildev hosts:
      o the bhm data volume handled in this example is higher than the
        default bril zone pt/utcp setup(which has not been changed),
        therefore you should use your own eventing server, checking out
        the configuration from svn with pt committed pool size
        increased. Which means you need 3 sessions.
      o when running you should NOT use any _inzone configuration, use
        additional -e /opt/xdaq/etc/default.profile  instead.
      o start eventing, MyProcessor, LocalMySource , in this order. Kill
        LocalMySource first, after several seconds, MyProcessor should
        show message about purging last lumi section on insufficient
        statistics.
      o start eventing,LocalMySource,MyProcessor, in this order.
        MyProcessor should show message about insufficient statistics on
        first lumi section.
