I represent a null interface; certain non-instance objects (strings and
integers, notably) are Entities.
Methods on this class are suggested to be implemented, but are not
required, and will be emulated on a per-protocol basis for types which do
not handle them.

I produce a stream of bytes for the request, by calling request.write()
and request.finish().

I will first attempt to retrieve an entity statically; static entities
will obscure dynamic ones. If that fails, I will retrieve the entity
dynamically.
