// class for Geant-shape SPHE
// derived from baseclass HGeoBasicShapes
//
// The functions readPoints(...) read from database or from file and store the
// input in the float-vector vol of class HGeoParam.
// ( point 0:   inner radius of the shell
//              outer radius of the shell;
//   point 1:   starting polar angle of the shell,
//              ending polar angle of the shell;
//   point 2:   starting azimuthal angle of the shell,
//              ending azimuthal angle of the shell; )
//
// The technical coordinate system of a SPHE, which sits in CAVE and is not
// rotated, is the laboratory system.
// It's the same as in Geant and therefore the matrix cgRot, which describes
// the transformation between these coordinate systems is the unity matrix.
