-------
Tornado future that resolves with:
model_changes : Nested AttrDict or None
Contains sets of added/removed request/sensor names
Example structure:
{'requests': {
'added': set(['req1', 'req2']),
'removed': set(['req10', 'req20'])}
'sensors': {
'added': set(['sens1', 'sens2']),
'removed': set(['sens10', 'sens20'])}
}
If there are no changes keys may be omitted. If an item is in both
the 'added' and 'removed' sets that means that it changed.
If neither request not sensor changes are present, None is returned
instead of a nested structure.
