// G4EllipticalCone
//
// Class description:
//
// G4EllipticalCone is a full cone with elliptical base which can be cut in Z.
//
// Member Data:
//
// xSemiAxis semi-axis, x
// ySemiAxis semi-axis, y
// zheight height, z
// zTopCut upper cut plane level, z
//
// The height in Z corresponds to where the elliptical cone hits the
// Z-axis if it had no Z cut. Also the cone is centered at zero having a
// base at zTopCut and another at -zTopCut. The semi-major axes at the Z=0
// plane are given by xSemiAxis*zheight and ySemiAxis*zheight so that the
// curved surface of our cone satisfies the equation:
//
// ***************************************************************************
// * *
// * (x/xSemiAxis)^2 + (y/ySemiAxis)^2 = (zheight - z)^2 *
// * *
