 DO NOT USE

 create tables of selected hits

 this function is only for debugging purpose to write
 down detector combined hits

Main and submain view 2d tracking
=================================

Define local 2d tracks by taking hit_p for the first and last
planes in main view and sub view

Loop over intermediate positions in the local tracks and compare
to the initially defined local tracks.
This might create additional ghost 2d tracks

Create a new TrackHit.  Indicate which combined hit it comes from as well
as which 2D track.  Also add this track to the 2D track from which it came

Copy trahit entries excluding the last detector hit
