A group is a MoRay concept. IIRC you can place anything in a group -
camera, lights, etc. OTOH a union is a POV-Ray CSG concept, an 'or' in
boolean terms. Some of MoRay's primitives do not exist in POV-Ray and
MoRay converts them into POV-Code, but I guess they can't be used in a
union within MoRay simply because they are not POVish. MoRay converts
groups to unions anyway so I think Lutz left the union in for clarity.
As of merge, it's like a union without inner surfaces.
