the functions file contains the following functions:

- echo_success()
     function for reporting the successful start of a program during bootup
- echo_failure()
     function for reporting the failure of the starting of a program
- echo_passed()
     function to report the passing of a system test
- echo_warning()
     function to report a warning

Not infront of a machine to verify the msgs that is being printed.

But "OK" for sccess, "FAIL" for failure", and we need to know about
what echo passed, and echo_warning prints and come up with something
represent this.
