Make GraphIndex accept nodes as key, value, references, so that the method
signature is closer to what a simple key->value index delivers. Also
change the behaviour when the reference list count is zero to accept
key, value as nodes, and emit key, value to make it identical in that case
to a simple key->value index. This may not be a good idea, but for now it
seems ok.
