Intermediate output during delta iterations

Hi,

Is there a way to persist every solutionSetDelta in delta-iterations 
(using the scala-API)?

Best,
Sebastian

Hey!

The Delta Iterations cannot persist intermediate states right now.

In general, output from within iterations should be possible with some
changes - I could give you some pointers how to do that, if you want to add
a patch.

With for loop iterations, this would be simpler, but for-loops cannot run
delta-iterations.
