/* Function:
bool SYS_CMD_Initialize( const SYS_MODULE_INIT * const init )
Summary:
Initializes data for the instance of the Command Processor module.
Description:
This function initializes the Command Processor module.
It also initializes any internal data structures.
Precondition:
None.
Parameters:
init - Pointer to a data structure containing any data necessary
to initialize the sys command. This pointer may be null if no
data is required because static overrides have been
provided.
Returns:
If successful, returns true.
If there is an error, returns false.
Remarks:
This routine should only be called once during system initialization.
