Requires that a set of tasks given by start times \a s and durations \a d
|
|
do not overlap in time. Tasks with duration 0 CANNOT be scheduled at any time,

but only when no other task is running. Start times are optional variables, so
|

that absent tasks do not need to be scheduled.

Assumptions:

- forall \p i, \a d[\p i] >= 0
