Abstract base class to define a fixed region.
Public interface
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.
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).
The LCRegion can be used in several Lattices and Images classes and functions to limit the area to operate on.
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.
