 System initialization file

 The tick is set to TICK ms.

 This file contains the 2 functions needed to initialize the system.

 These functions register the following levels:

 an EDF   (Earliest Deadline First) level
 a  RR    (Round Robin) level
 a  TBS   (Total Bandwidth Server) level 0.1 Us
 a  TBS   (Total Bandwidth Server) level 0.3 Us
 a  Dummy level

 The TBS bandwidth is TBS_NUM/TBS_DEN


 It can accept these task models (into () the mandatory fields):

 HARD_TASK_MODEL (wcet+mit) at level 0
 NRT_TASK_MODEL  at level 1
 SOFT_TASK_MODEL (wcet, periodicity=APERIODIC) at level 2,3
