Definition of color chain members.

Found next color index in evolving system.

Try to use find next color index in system of mother (if different), and then exit.

Try to find incoming particle in other systems, i.e. if the current system arose from a resonance decay.

For gluon, just match both colors.

Loop through, find color and attach subsequent particles to chain.
