0003  * \author L. Gray
0004  *
0005  * A transient data class used to wrap a Correlated LCT
0006  * and give access to its eta and phi coordinates.
0007  * This is essentially the merging of a CSCDetId and a CorrelatedLCT
0008  * into one class.
0009  *
0010  * \remark Takes the place of both L1MuCSCCorrelatedLCT and L1MuTrackStub
