I am just dropping some more thoughts here ;-)
The interface seems a bit confusing. Right now, one has to first create the
iteration from the graph and then tell the graph to run it:
``` java
GatherSumApplyIteration iteration =
graph.createGatherSumApplyIteration(gather, sum, apply);
Graph result = graph.runGatherSumApplyIteration(iteration);
```
What was the reason to not go simply for
``` java
Graph result = graph.runGatherSumApplyIteration(gather, sum, apply);
```
If the reason was additional parameterization of the iteration, would it be
nicer do go for the following?
``` java
GatherSumApplyIteration iteration =
graph.createGatherSumApplyIteration(gather, sum, apply);
iteration.configureInSomeWay(...);
Graph result = iteration.result();
```
