Detailed Description

A class for detailed particle trajectory representation. It is used during trajectory building to "grow" a trajectory. The trajectory is represented as an ordered sequence of TrajectoryMeasurement objects with a stack-like interface. The measurements are added to the Trajectory in the order of increasing precision: each new TrajectoryMeasurement is assumed to improve the precision of the last one, normally by adding a constraint from a new RecHit. However the Trajectory class does not have the means to verify that measurements are added in the correct order, and thus cannot guarantee the order, which is the responsibility of the TrajectoryBuilder. The Trajectory provides some security by allowing to add or remove measurements only on one of it's ends, with push(TM) and pop() methods. The last measurement in a Trajectory can thus be either the innermost (closest to the interaction point) or the outermost, depending on the way the Trajectory was built. The direction of building is represented as a PropagationDirection, which has two possible values: alongMomentum (outwards) and oppositeToMomentum (inwards), and is accessed with the direction() method.
