[CakeML-Dev] reusing a CF specification

[Michael.Norrish at data61.csiro.au]

I just copied the code out of basisProg; that has

- - 
val _ = ml_prog_update (open_module "Word8");

val _ = append_dec ``Dtabbrev [] "word" (Tapp [] TC_word8)``;
val _ = trans "fromInt" `n2w:num->word8`
val _ = trans "toInt" `w2n:word8->num`

val _ = ml_prog_update (close_module NONE);
- -

    Did you store the specification you proved?
