0000183: Store/recall random number seeds in hdgeant/mcsmear
A common debugging tool is to record the random number seeds for every simulated event so that a specific event may be re-simulated without having to re-simulate all prior events in the file. This functionality was discussed at a recent offline meeting and it was decided it should be added to hdgeant and mcsmear.

Functionality was added to HDDM and hdgeant with revision 8657. This was tested with 100 b1pi events where "SWIT 2 2" was set printing every call to gustep. The output was captured to a file. The program was then re-run, but with the output of the first round used as input to the second. The value of RNDM was also changed to ensure no residual use of it was affecting things. The two captured output files showed no differences in the physical parameters simulated for the 100 events.
