[Halld-offline] HDParSim and tracking

[David Lawrence]

Hi All,

    Thanks Mihajlo. You are correct. The DPhoton objects now look for 
DTrackTimeBased objects (see attached callgraph) which is activating 
full tracking. This needs to be corrected for HDParSim so that it 
generates DTrackTimeBased objects in addition to DPhoton objects using 
the resolution tables. I'll take care of this and will send another 
e-mail once it is complete. I may not be able to get it completed today 
though.

Regards,
-David
