00006 //  various utilities to extract information from the particle ID
00007 //
00008 //  In the standard numbering scheme, the PID digits (base 10) are:
00009 //            +/- n nr nl nq1 nq2 nq3 nj
00010 //  It is expected that any 7 digit number used as a PID will adhere to 
00011 //  the Monte Carlo numbering scheme documented by the PDG.
00012 //  Note that many "new" particles not explicitly defined already 
00013 //  can be expressed within this numbering scheme. 
00014 //
00015 //  These are the same methods that can be found in HepPDT::ParticleID
