 Scheduler Rules
Precedence: If two events occupy the same slot, this is the precedence:
1. StartTime Bootups take ultimate precedence during the bootup minute, and
are treated as normal events afterwards ( if they repeat).
2. Repeating Bootups take second precedence during the bootup minute.
3. One-shots take precedence over Loops.
4. Finites take precedence over infinites during their period of execution.
5. Finites started on a later slot will take precedence over earlier finites.
