0005  * \class GEMCSCSegAlgoRR

0006  *

0007  * This algorithm is very basic, there is no attempt to deal with ambiguities, such as noise etc.

0008  * The GEMCSC track segment is built starting from a CSC segment and trying to match GEM rechits.

0009  * The GEM rechits are searched inside a conigurable (eta,phi) window and associated to the segment.

0010  * This collection of GEM rechits and CSC semgent is called the GEMCSC Ensemble. <BR>
