[Clas12_high_luminosity] Simulation Update

[Whitney R. Armstrong]

Hi Volker,

I have produced two graphs, however, with limited statistics (~1.5M). Many more 
jobs are running on the farm right now.

The first shows (in cylindrical coordinates) the radial vs z position of the 
starting point for the trajectory that ultimately produced at hit in the DC.

The second shows the wire number of the DC hit vs the same z as above. 

I will post these results on the wiki when I have gathered more statistics. 

Your comments and questions are appreciated.

Cheers,
Whit
