This is the declaration of the ColourReconnector class.
This class does the nonperturbative colour rearrangement, after the
nonperturbative gluon splitting and the "normal" cluster formation.
It uses the list of particles in the event record, and the collections of
"usual" clusters which is passed to the main method. If the colour reconnection
is actually accepted, then the previous collections of "usual"
clusters is first deleted and then the new one is created.
NB) This class must be implemented!
