This branch will introduce autogeneration of documentation.

Right now, all I've done is added a empty routine.
creates the files and title/abstract/body lines.

Much left to do:

* interpret 'value' section
* go recursive; handle search/choice functions
* writing main page
* don't zap clean the directory; just the *.RST files
* import bulk text where requested.
further progress
more work done on the RST documentation generator.

Next: have the interp of a MARDS-schema automatically add:
   value
      type string
if value is missing. Or add 'type string' if type is missing. Those are
the explicit defaults.
'value' and 'type' now auto-generate if missing.
sub docs for 'search' now autogenerate. choices now display.
finished with round one changes. Basically works. Needs finesse now.
