Detailed Description

This class holds info on a parton resolved inside the incoming beam, i.e. either an initiator (part of a hard or a multiparton interaction) or a remnant (part of the beam remnant treatment). The companion code is -1 from onset and for g, is -2 for an unmatched sea quark, is >= 0 for a matched sea quark, with the number giving the companion position, and is -3 for a valence quark. Rescattering partons properly do not belong here, but bookkeeping is simpler with them, so they are stored with companion code -10.
