// class for Geant-shape PCON
// 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:   number of planes perpendicular to the z axis where the dimension 
//              the section is given, (maximum of 6 planes);
//   point 1:   azimutal angle phi at which the volume begins,
//              opening angle dphi of the volume,;
//   point 2ff: z coordinate of the section,
//              inner radius at position z,
//              outer radius at position z;
//
// To position a volume in its mother different functions are called in the
// routine posShape(...) depending on the shape of the mother. Uptil now it's
// only possible to position a PCON in a mother with shape PGON or PCON
// In these functions posIn...(...) the position of the Geant-origin in the
// intrisic coordinate-system of the detector is calculated and stored in the
// vector geaPos of class HGeoParam. This information is needed to calculate the
// position of daughtervolumes. The Geant-position of the volume inside its
// mother is calculated and stored in the vector pos of class HGeoShapePar. Where
// needed a Geant-rotationalmatrix is created via Geantroutine GSROTM and the
// number stored in nRot of class HGeoShapePar. Otherwise nRot is set to 0.
