System initialization file
The tick is set to TICK ms.
This file contains the 2 functions needed to initialize the system.
These functions register a set of scheduling modules, in a fixed or
dynamic priority way...
It can accept these task models:
HARD_TASK_MODEL (wcet+mit) at level 0
SOFT_TASK_MODEL (periodicity=APERIODIC) at level 1
NRT_TASK_MODEL at level 2
SOFT_TASK_MODEL (periodicity=APERIODIC, wcet (only if TBS) ) at level 3,4
