 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 CBS (Costant Bandwidth Server) level
 a Dummy level

 It can accept these task models:

 HARD_TASK_MODEL (wcet+mit) at level 0
 NRT_TASK_MODEL  at level 1
 SOFT_TASK_MODEL (met, period) at level 2

 This file is similar to the configuration of Hartik 3.3.1
