// \brief A formulation of a cylinder with Gaussian distribution
//
// \author
//   J.L. Mundy
// \date  March 04, 2003    Initial version.
//
// Intrinsic parameters
//  - xy_sigma_     - the in-slice Gaussian std-dev.
//  - z_sigma_      - the across-slice Gaussian std-dev.
//  - length_sigma_ - truncation of the cylinder axis.
//
// Extrinsic parameters are:
//  - x_origin_     - x coordinate of the cylinder origin
//  - y_origin_     - y coordinate of the cylinder origin
//  - z_origin_     - z coordinate of the cylinder origin
//  - elevation_    - elevation orientation of cylinder axis (deg)
//  - azimuth_      - azimuth orientation of the cylinder axis (deg)

//  Modifications
//   10-sep-2004 Peter Vanroose Added copy ctor with explicit vbl_ref_count init
