UNSET
Usage: unset variable
- in this example we have a var %testvar% we no longer need:
set testvar hops happily along %echo% %self.name% %testvar%
unset testvar
- please note - if we had made the var global, it'd be gone instead.
Remove the variable from the global variables of this script, or if not
found there, from the script.
