Detailed Description

Base abstract class for tools used to fit tracks.

The virtual function makeTrack comes in different versions, one for each possible input (Trajectory, TrackTrajectory, Track), both using const references and art pointers as input). The functions return a bool corresponding to the success or failure status of the fit.

The only purely virtual function is the one for input Trajectories (by default the other two just forward the call to it). Its arguments are the const inputs (Trajectory, TrajectoryPointFlags, track ID) and the non-const ouputs (mandatory: outTrack and outHits; optional outputs stored in OptionalOutputs).

In case other products are needed from the event (e.g. associations to the input), they can be retrieved overriding the initEvent function.

The tool is not meant to put collections in the event.

Requirements are that a Track has at least 2 points, that it has the same number of Points and Momenta, that TrajectoryPoints and Hit have a 1-1 correspondance (same number and same order).
