// ITS step manager and geometry class for the ITS SDD test beam geometry
// of Summer 2003 and later.
// At present, the geometry and materials need to be checked against the
// proper geometry of the 2003 test beam. In addition, because the SSD
// used in the test beam are single sided, the second side needs be ignored.
// This can cause some problems with the SSD reconstruction code.
