Loads a model from the server using the collection type and the id. Returns null if the pod could not be found or loaded.
@param  string $collection The collection to load from. For graphs, this can only be "vertex" or "edge".
@param  string $id         The id (key in ArangoDB jargon) of the document, edge or vertex.
@return AModel
