0004 /** \class TSGForRoadSearch
0005  * Description: 
0006  * this class generates hit-less TrajectorySeed from a given Track.
0007  * the original error matrix of the Track is adjusted (configurable).
0008  * this class is principally used for muon HLT.
0009  * for options are available:
0010  * - inside-out seeds, on innermost Pixel/Strip layer.
0011  * - inside-out seeds, on innermost Strip layer.
0012  * - outside-in seeds, on outermost Strip layer.
0013  *
0014  * regular operation is one seed per track, but optionnaly, more than one seed can be madefor one track.
