Order of Modules for TACCalibration and EnergyCalibration

[NicoleRodriguezCavero]

We need to verify that doing the TACCalibration module (and TAC cuts) before/after the EnergyCalibration module yields the same results. Back in February, if the EnergyCalibration module was not required first and the nearest neighbors were being read out, the TAC cuts were failing for NN and direct hits. From Robin on February:

Preliminary tests don't see a difference when EnergyCalibration is required vs not before the TACCalibrationFrom module. From Nicole on September:

There are two remaining issues with assigning a definitive order of calibrations:

• We want to be able to use the TACCalibration module (and respective TAC cuts) before the EnergyCalibration module for Robin's energy calibrations. This points to using AddPreceedingModuleType(MAssembly::c_TACCalibration) on the EnergyCalibration module, BUT:

• Future students will need to only use the TACCalibration or EnergyCalibration modules uniquely for detector effects analysis, so assigning a requirement might over-complicate their work.

In case that we get the same results, no matter if we perform the energy calibration or the TAC calibration first, why would we need to require a fixed order?

If there truly is no difference, and there is a good reason to not constrain this order (for future flexibility of applying some but not all calibrations), then it's okay to leave both orders as available options. I was uncomfortable with people having different orders of operation without a confirmation that the results aren't identical, but if that's not the case, then we're okay.

Then someone should revisit that the order does not matter (anymore)
