Re:TTY-Exit: terminal exit codes for humans and machines

This library improves the situation as:
* It includes default user-friendly error messages for all the built-in exit codes. For example, the code 64 will print " "ERROR(64): Command line usage error" to stderr.
* Machines, e.i. programs that, for example, watch over an executable can decided based on the error code what to do. If the program is interrupted by Ctrl-C then the parent program can handle the situation gracefully.
I totally agree that an example of using an exit code in a parent program would be beneficial.
