Some Ideas
---------------------
  PSP  Stack Pointer
  RSP  Return Pointer
  W    Working Register

Having these two would make some of the primitives easier to implement.
Thanks ASau!

  D    DICTIONARY
  H    HERE

Using these we can control the current point HERE or in the DICTIONARY.
It would be the basis for "forgetting" words (without destroying their
implementation)


Clean up primitives, implementation of drivers, documentation, source
code layout.


Keep isolated for now, but make easy to extend into the full Retro 7
/src layout. Will colaborate with tcn on this...


Finish native compiler, test, use to deliver applications (basic editor,
etc) for Retro 7.


Support for IF/THEN (working?) and TIMES/REPEAT (suggested by ASau)
