set_start_based_duration

Purpose
If the task is allocated to this resource, the duration will take the given 'duration' value if the start of the task is between the given interval:
(t1 <= task.start <= t2) and (task.assign(r) = 1) ⇒ task.duration = duration
This method can be called repeatedly to specify different durations on different intervals. Calling it successively with intersectings intervals will override existing values on the intersection. Also, propagation should not be called between successive calls.
Note: All values not included in any of the given intervals will be forbidden for the start variable.
