Checks that all targets are reachable from the starters. This implementation tries to shortcut the check adding starters incrementally. Ordering the starters by relevance can improve performance in the average case.

Parameters

targets:Collection<RevObject>: objects to check for reachability from the starters
starters:Stream<RevObject>: objects known to be reachable to the caller

Returns:Optional<RevObject>

Optional a single unreachable target if there are any (there could be more). Empty optional means all targets are reachable.
