Detailed Description

Helper class to aid the creation of a recob::Track, keeping data vectors in sync.

Helper class to aid the creation of a recob::Track, keeping output data (vectors of recob::tracking::Point_t, recob::tracking::Vector_t, recob::TrackTrajectory::PointFlags_t, recob::Hit, and trkmkr::OptionalOutputs struct) in sync. It internally stores and uses a trkmkr::TrackTrajectoryCreationBookKeeper object. Elements of those vectors are added sequentially using the addPoint functions. Once all points have been added a call to the function finalizeTrack, builds the track moving the content of the vectors.
