[EXTERNAL] corrections & suggestions for dreiding docs

Hi Andrew - didn't get to this before the break ...
will take care of it in the new year.

Did you get any feedback from Tod on these changes?

Happy holidays,
Steve

Just posted a patch for all of this - it all looks good.
The doc pages should now be clearer to users
who want to use Dreiding as they have in other codes.

Thanks,
Steve
