Subject: [PATCH] Specialize FieldTraits for MultiTypeBlockVector
This allows other code to access field_type and real_type for a MultiTypeBlockVector
using the FieldTraits class. Caveat: in principle, individual entries of a
MultiTypeBlockVector could use different field_types. The implementation always
returns the first one.
