Detailed Description

Description: this class generates hit-less TrajectorySeed from a given Track. the original error matrix of the Track is adjusted (configurable). this class is principally used for muon HLT. for options are available:

inside-out seeds, on innermost Pixel/Strip layer.
inside-out seeds, on innermost Strip layer.
outside-in seeds, on outermost Strip layer.

regular operation is one seed per track, but optionnaly, more than one seed can be madefor one track.
