System initialization file
 
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
SOFT_TASK_MODEL (met, period) at level 1
NRT_TASK_MODEL at level 2
 
This file is similar to the configuration of kernel/init/hartik3.c
 
TICK is set to 0 (one-shot timer is used)
