LY Vacuum control modification for PT-120
Modified Software interlock to allow the Cold Cathode gauge to be turned on due to problems with pirani gauge.  This is the older style of two gauges  A being the pirani and b being the cold cathode. Patrick forced the Value of COLD_CATHODE_HIGH_LIMIT_TORR to 1 on LVEA LY vacuum control computer.  This allowed the Cold cathode to turn on.  This will be in place until we vent and can replace the guage.
