public interface Result

The execution result returned by the Task's Function. Each Result has an associated execution Context from where the Function was executed.
At each execution step, a Function may consume none, one or two inputs. Independently, the function can produce none, one or two outputs.
When a Result is committed to a WorkSpace, the outgoing Links of the Context will be filled with the outputs. Accordingly, the ingoing Links will be consumed.
