EAC Control

Build Labview routine to control EAC instead of EIS.

• mult on off
• CAE/CRR and Epass
• KE, span and fraction
• quadrupoles

EIS quits if LV cable disconnected and GPIB write fails - no error handling

Changes needed to FPGA:

1. remove DAC1 mode, not supported?
2. Decimate should have a separate Delta T routine, 32 bits, call once per transfer cycle, no need to slice into 10 us intervals then sum back to 10 ms...

Changes to PC GUI

1. Add gpib controls
2. add noise calculation
3. decimate by summation
