   Created version 2_0_0.  
   
   Added capacitor C22 across thermocouple input.
   Added thermocouple grouning jumper as resitor R25.
   Fixed U7 opamp backward in+ and -.
   Added second resitor R24 for place to make up 66.7K

 TBD resistor values
 
  R1,8,12,13,14 = 1K
  R16 - 23 = uninstalled
  R4 = 2.1k 1% - this is the gain resistor for the pressure sensors (g=100)
  R10,11 = 10K
