[Dsg-htcc] HTCC gas system monitoring

[Marc McMullen]

Hi Nick, 

I have replaced the source distribution with a Start Up application and remotely rebooted. Everything came back fine, including the heartbeat. So I think all is fixed.

Hi Nick, 

I loaded a new source distribution on the cRIO, so if you need to reboot 
you will get flow, I am still working the heartbeat after manual reboot.

Updates of CO2 flow also stopped at the same time, but, meanwhile, humidity and pressure continued to update until now. Rebooting the softioc was just a check to see if the problem could be there and confirmed it is not.
