Detailed Description

The SubProcessHandler class is used to handle a set of MEBase objects together with a PartonExtractor.

It is used by the StandardEventHandler to group together different ways of extracting partons from incoming particles with associated hard parton-parton matrix elements.

Just as the EventHandler class, a SubProcessHandler keeps a full set of HandlerGroups, which may be filled with defaults which overrides the ones specified in the EventHandler in each event the SubProcessHandler is chosen.

The SubProcessHandler has also a Cuts object which is responsible for restricting the kinematics of the sub-process and produced collision. This object takes precedence over the one in the EventHandler in each event the SubProcessHandler is chosen.
