Add delayed helicity analysis for Mott_Sample and Mott_SemiInt Modes. Delayed analysis is already included for Scalers and PEPPo_Int Modes.
Modify decoder for the updated Mott_SemiInt mode. Started: /work/idaq/Mott/Analysis/1, Runs: 7642, 7672. Sample: 7673
Update MottOnline
Replace "PEPPo" with "Mott" in scripts, decoder, ... .

* New Delayed Helicity Readout Scheme for Physics Events Trigger

* Things to do to speed up the DAQ and reduce deadtime:

Use the new SemiIntFast Mode:
1. Upgrade the time-of-flight readout to the FADC TDC mode
2. Upgrade the scalers readout to the FADC Scaler mode
3. Add Block Readout
Reduce the Mott Trigger rate by rejecting low energy electrons or dump events:
1. Increase E-detector discriminator thresholds
2. Veto dump events using beam timing signal

* Max's list of random things

need to get the signal propagation vs. electron TOF delay for the helicity decoder correct
