// <synopsis>
// The LCRegion class is the abstract base class for various types
// of LCRegion's (e.g. LCRegionEllipsoid, LCRegionBox).
// It contains the minimal bounding box of the region and, if needed,
// a mask with the same shape as the bounding box. A mask element
// is true if the element is inside the box.
// <p>
// Each LCRegion object must be able to convert itself to and from a record.
// In that way they can be made persistent (in for example a Table).
// <p>
// The LCRegion can be used in several Lattices and Images classes and
// functions to limit the area to operate on.
// </synopsis>
// <example>
// <srcblock>
// </srcblock>
// </example>
// <motivation>
// The Slicer class is too limited as a region, because it can only
// describe a rectangular region. Specialized classes are needed to
// describe arbitrary regions. They need a base class to combine them.
// </motivation>
