Iss1147 -- Add hole-accounting to tracks

[bloodyyugo]

Closes #1147

Add hole on track--defined as the layer where the track is projected to go through the sensitive area of a sensor but no hit is included in the track.

This is included in the Track object's _subdetId (see here Track). We already use this to account for the layer numbers with hits on track, setting _subdetId[layer]=1 for a hit on track. For a hole, I've set _subdetId[layer]=-1.

Looks good to me, thanks!

Only comment: I'm not sure if it's the GitHub viewer, but it I'd be nice to intend your code after the definition of a method. Would be a lot easier to read.

That is weird, because in emacs these are indented correctly.

Maybe run "untabify" in Emacs to turn tabs to spaces?
