Detailed Description

A factory that can combine the functionality of several 'trajectory factories'. At construction time, it is given an ordered list of what kinds factories it should use. When called, all the factories are called one after each other,

• either until one of them gives a result
• or until all factories are really called. This is determined by the useAllFactories flag.

Example: Combine TwoBodyDecayTrajectoryFactory and ReferenceTrajectoryFactory with useAllFactories = false. In case the former can't produce a trajectory from two given tracks, the tracks can still be used for 'ordinary' reference trajectories (see also TrajectoryFactories.cff).
