Detailed Description

Define a follow on class.

The idea of this is that in air-crew scheduling problems crew may fly in on flight A and out on flight B or on some other flight. A useful branch is one which on one side fixes all which go out on flight B to 0, while the other branch fixes all those that do NOT go out on flight B to 0.

This branching rule should be in addition to normal rules and have a high priority.
