Fixed tests due to async var creation, plus minor stuff
A variable is created synchronously but its data is get in background
so tests have now to wait until the variable is ready before checking its
state.
VC should have a [] operator, it's a model feature.
The new data provider interface implies that each call only ask for
one range, this has been reflected in its parameters.
