// <synopsis>
// The WCUnion class is a specialization of class
// <linkto class=WCCompound>WCCompound</linkto>.
// It makes it possible to take the union of 2 or more image regions.
// Note that only world coordinate regions can be used in a compound,
// thus an LCSlicer object is not allowed in a union.
// <p>
// The union of regions is the collection of the pixels masked-on
// in any region.
// Note that the bounding box of a union is determined by the outermost
// pixels. It means that if regions are very far apart, the bounding
// box of the union is very large and therefore inefficient.
// <p>
// The regions in a union can have different axes and dimensionalities.
// The axes and dimensionality of a union are determined by the
// collection of all different axes in its regions. Each individual region
// will be auto-extended along the axes not being part of the region.
// E.g. one can define a WCBox with axis RA and another WCBox with
// axis DEC. The union will be 2-dim with axes RA and DEC. The first
// box will be auto-extended to cover the DEC axis, which results
// in a 2-dim box with its DEC axis the length of the image's DEC axis.
// Similarly the second box will be auto-extended to cover the RA axis.
