of using a colon to specify a parent class in a GIB class definition,
"extends" is now used. If no parent class is specified, it now defaults to
Object.
and probably has enough bugs to leave the Orkin man scratching his head,
but it works and allows you to do neat things like write classes in GIB
(amazing!) and subclass builtin classes (which are Object and Thread at the
moment, Hash should be coming soon as a replacement for stem and leaf
variables).
