Detailed Description

The HEPEUP class is a simple container corresponding to the Les Houches accord (hep-ph/0109068) common block with the same name. The members are named in the same way as in the common block. However, fortran arrays are represented by vectors, except for the arrays of length two which are represented by pair objects.
