 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
