tests the geometrical compatibility of the Det with the predicted state. The FreeTrajectoryState argument is propagated to the Det surface using the Propagator argument. The resulting TrajectoryStateOnSurface is tested for compatibility with the surface bounds. If compatible, a std::pair< true, propagatedState> is returned. If the propagation fails, or if the state is not compatible, a std::pair< false, propagatedState> is returned.

Returns all Dets compatible with a trajectory state according to the estimator est. The startingState should be propagated to the surface of each compatible Det using the Propagator passed as an argument. The default implementation should be overridden in dets with specific surface types to avoid propagation to a generic Surface

Similar to compatibleDets(), but the compatible Dets are grouped in one or more groups. Dets are put in the same group if they are mutually exclusive for track crossing, i.e. a reconstructible track cannot cross more than one Det from a group. Pathological tracks (spirals etc.) can of course violate this rule.
The DetGroups are sorted in the sequence of crossing by a track. In order to define the direction of crossing the Propagator used in this method should have a defined direction() : either "alongMomentum" or "oppositeToMomentum" but not "anyDirection".
The three signatures of this method differ by the input trajectory state arguments: the starting state can be a TrajectoryStateOnSurface or a FreeTrajectoryState, and the state on this CompositeDet may be already known or not. The last two arguments are as for the method compatibleDets().
First signature: The first argument is a TrajectoryStateOnSurface, usually not on the surface of this CompositeDet.
