Generic Wrapper for the fortran HEPEVT common block.
This class is intended for static use only - it makes no sense to instantiate it.

check for problems with HEPEVT common block
This method inspects the HEPEVT common block and looks for inconsistencies in the mother/daughter pointers

write information from HEPEVT common block
dumps the content of this HEPEVT event to ostr (Width is 80)

static |
write particle information to ostr
dumps the content HEPEVT particle entry i (Width is 120) here i is the C array index (i.e. it starts at 0 ... whereas the fortran array index starts at 1) So if there's 100 particles, the last valid index is 100-1=99
