This is a first cut of a abstract forth machine. An attempt to make a forth machine that is not bound to a bit width or memory model. At the moment it is just a list processor.
completer.go - auto completion functions for readline
define.go - colon and semi colon defns
dictionary.go - the searchable dictonary struct
extra.go - extra words for visiablilty
fth.go - the main functions for the Abstract Forth machine
init.go - base setup words
interface.go - external interface functions
machine.go - the forth and options struct
rstack.go - return stack (need to work towards normal stack impl)
stack.go - the data stack
word.go - the word struct and interface (needs more work)
