// <synopsis>
// The LCUnion class is a specialization of class
// <linkto class=LCRegion>LCRegion</linkto>.
// It makes it possible to extend a LCRegion along straight lines to
// other dimensions. E.g. a circle in the xy-plane can be extended to
// a cylinder in the xyz-space.
// includes the union border.
// It can only be used for a lattice of any dimensionality as long as the
// dimensionality of the (hyper-)union matches the dimensionality of
// the lattice.
// <p>
// The center of the union must be inside the lattice
