[Clas12_rich] RICH air cooling system diagram update and hardware list, review tasks questions

[Marco Contalbrigo]

Dear Tyler and George, 
which kind of cRio do you propose (National) ?

To my understanding this is the (only) unit should interface to the 
slow-control as can provide all the wanted information about the
cooling system. Thus I would like to check if anything similar (or
equal) is already working under epics.

Thanks, Marco.
