Fix mchitcount not being cleared at start of Decode
Move hit-related search functions from Tracker to Plane. Set MC bits.

Implement the analysis code for setting the hit-related status bits in
MCTrackPoint. The status word now provides much more detail about the
status of hit reconstruction, nearby noise hits, contaminated hits, etc.
Sort the GEM strip numbers in Decode! Warn if and skip any duplicates
To reduce reliance on other headers, include THaEvData.h in WirePlane.cxx
When marking MC track hits as found, don't require the MC hit to be the closest
Fix return type of SetPlaneBits::GetBits()

Probably a leftover of copying this template from another...
For MC data, calculate planepattern of MC hits used in track fits
