   #      - Removed creation of the pulic_html directory.  This directory
   #        can now be added in two ways:
   #        o The user can add it themselves if they want some local web
   #          space which may or may not contain construction items.
   #        o LonCapa will add it if/when the user is granted an Author
   #          role.
