// G4Cons
//
// Class description:
//
// A G4Cons is, in the general case, a Phi segment of a cone, with
// half-length fDz, inner and outer radii specified at -fDz and +fDz.
// The Phi segment is described by a starting fSPhi angle, and the
// +fDPhi delta angle for the shape.
// If the delta angle is >=2*M_PI, the shape is treated as continuous
// in Phi
//
// Member Data:
//
// fRmin1 inside radius at -fDz
// fRmin2 inside radius at +fDz
// fRmax1 outside radius at -fDz
// fRmax2 outside radius at +fDz
// fDz half length in z
//
// fSPhi starting angle of the segment in radians
// fDPhi delta angle of the segment in radians
//
// Note:
// Internally fSPhi & fDPhi are adjusted so that fDPhi<=2PI,
// and fDPhi+fSPhi<=2PI. This enables simpler comparisons to be
// made with (say) Phi of a point.
// History:
// 19.3.94 P.Kent: Old C++ code converted to tolerant geometry
// 13.9.96 V.Grichine: Final modifications to commit
