       This class represents an instance of a C "union".  This class can be created using "new" on the generated
       class, if that was specified for the FFI::C::UnionDef, or by using the "create" method on
       FFI::C::UnionDef.

       For each member defined in the FFI::C::UnionDef there is an accessor for the FFI::C::Union instance.
