/**
* \class TrackStub
* \author L. Gray
*
* A transient data class used to wrap a Correlated LCT
* and give access to its eta and phi coordinates.
* This is essentially the merging of a CSCDetId and a CorrelatedLCT
* into one class.
*
* \remark Takes the place of both L1MuCSCCorrelatedLCT and L1MuTrackStub
