Fix a typo in the name of a histogram.
Place histo in the correct directory.
Rework the top-level cut flow.

Make mu stop selection less sensitive to TGT PC asymmetries.
Extend selection up to a "downstream decay candidate" in MuCapture, do not stop at mu stop.
Plot cut flows with "hist text" by default.
Add a common time cut: cutting on window time (rather than track time) reduces a time resolution systematic on the normalization.
Remove MuCapStreamAnalysis; update MuCapTrkAnalysisHF and call it directly from the top level.
Rearrange histograms and ROOT directories.  No functionality change.
Remove redundant window time histograms.
A more careful handling of multiple track cases.
Set default track-muon offset cut to 1.5 cm, and re-order track selection cuts.
Implement track quality plots.
Turn off a debug printout.
