HistogramFactory: add support for TProfile
Add tracking resolution plots.
More momentum resolution plots.
Revert "Adjust the binning"---undoing TDC PID calibration commits.

This reverts commit 2893e61639aa86eb7738ea03583a1f70ef6d346e.
Revert "An attempt at TDC PID calibration."

This reverts commit 941bf4931164f8e5f864f8a4e5463b0fb3ae1e5a.
Remove some unused histograms.
A provision to use different cut sets for different tracking analysis instances.
Use a dedicated cut set to select a sample of DIOs for normalization.
Return the preferred PID variable from the histogram filling code.
Don't run resolution code on real data events.
Define a sample of negative tracks with loose cuts and use it to veto capture candidate events.
Set up exclusive analysis channels for contained and non-contained tracks.
