Sorry for late reply.

A small comment: Gee.HashMultiMap<P,HashMap<S,V>> - Is there a reason
why it is a multimap? It is {P -> {S -> V, S' -> V'}} differ then {P ->
{S -> V}, P -> {S' -> V}}? What's {P -> {S -> V}, P -> {S -> V'}}?

Regarding rest - what's the usecase/advantage over using just Gee.Map<P,
Gee.Map<S, V>>?
