// <etymology>
// HogbomCleanImageSkyModel implements the Hogbom Clean algorithm.
// It is derived from <linkto class=SkyModel>SkyModel</linkto> and uses the
// fortran code in hclean.f
// </etymology>
//
// <synopsis> 
// The Hogbom Clean is the standard classic clean.
//
// The Hogbom Clean is implemented using the 
// hclean.f code.
//
// Masking is optionally performed using a mask image: only points
// where the mask is non-zero are cleaned. If no mask is specified
// all points in the inner quarter of the image are cleaned.
// </synopsis> 
//
// <example>
// See the example for <linkto class=SkyModel>SkyModel</linkto>.
