Subject: EPICS and MEDM screen for Hartmann sensor - part 2 

I added the camera parameters to EPICS and the MEDM screen. These are available as channels now in EPICS and eventually there will be a python script that writes the EPICS value to those channels, but right now it is just a python script that reads the values off the Dalsa camera.

I updated the channels in /cvs/cds/caltech/chans/daq/C4TCS.ini so that these are saved to the daq and I also restarted the daq daemon.

The python script that gets the camera parameters is here: scripts/Dalsa1M60/GetCameraParameters.py and the script that writes the parameters to the EPICS channels is here scripts/dalsa_to_epics.py.

These are attached as is C4TCS.ini and HWS.db which defines the new channels.
