xpdAcq Plans for loop annealing using temperature controller

Expected Behavior

Users wanted to use eurotherm to do loop annealing as the followings:
go from Temp T0 to T1 and back to T0 and collect data on three temperatures point with shutter controls ON for dark control and for t-sec data acquisition
Then move to next step goes from T0 to T1+T_Step and back to T0. This repeats until Tmax in a loop.

Current Behavior

Tramp & Tlist works with eurotherm but difficult to do looping.
New Ophyd object is being implemented to accommodate eurotherm call back and sensor failure sensing.

Possible Solution

Use eurotherm the same way as cryostream(cs700) for start and stop triggering detectors and somehow stop the acquisition when the sensor signal is 0 ( generated by a PV and being implemented into Ophyd)

Steps to Reproduce (for bugs)

1. Test the current Ophyd for eurotherm for Tramp/Tlist
2. Test how current Ophyd for eurother works with sensor signal.
3. Then test a loop with triggering detector and shutter controls

Priority

This feature will be used for users at XPD in end of February and at PDF beamline during end of March in 2019-1 cycle.
The PDF experiment in March involved proposal from Ian Robinson's group involving Tadesse from BNL and Soham from CU.

A quick thought (also for myself).

The annealing scan plan, along with the shutter and dark collection requirements, can be easily done with existing Tlist by feeding corresponding temperature points, if the eurotherm object can be triggered as cs700.
