Detailed Description

Helper class saving all the needed information to compute strips for a particular cathode board.

This class holds a reference to an Element representing a specific cathode board, and the stripConfiguration: the various pitch vectors to compute a particular strip on this cathode board.

The method getStgcStrip performs the computation of the requested strip in quadruplet coordinates
