I revived the test midas experiment on midtis06. We can start using it to
develop the online connection to the root gui. Here are the instructions
on running things:
 - login to midtis06
 - set ROOTSYS to /send/home/olchansk/daq/root
 - cd /send/home/olchansk/daq/root
 - ./start_daq (four xterm windows should open:
   1) mhttpd (on port 8080). Point a web browser to http://midtis06:8080
   2) odbedit
   3) a front end
   4) an analyzer)
 - run ~olchansk/daq/midas/linux/bin/rmidas
   enter "midtis06" in the "hostname" box.
   five histogram names should appear in the list on the left: CADC00
through 03 and ADCSUM. Click on the names to see the histograms.
 - start a run (from a web browser, or enter "start" in odbedit)
 - the frontend window should count 100 events/sec.
 - click on the rmidas "update" button, the counts should increment.
This is all done by vanilla ROOT and MIDAS.

The ROOT code to access the MIDAS histograms is in
~olchansk/daq/midas/src/rmidas.c, functions:
 - ConnectServer()
 - GetHistoList()
 - GetHisto()
 - ClearHisto()
