     Does all phase 1 processing of file creation:
     Ensures that the user provides a new filename, adds proper extension
     if needed and that the file does not already exist, if it is a html,
     problem, page, or sequence, it then creates a form link to hand the
     actual creation off to the proper handler.
   
   Parameters:
   
   =over 4
   
   =item   $request  - Apache Request Object [in] - Server request object for the
                  current url.
   
   =item   $username - Name of the user that is requesting the directory creation.
