// FUNCTION:
//   objectTag
//
// DESCRIPTION:
//   This object is used as a shim to launch the appropriate 
//   server behavior for the current server model.  The individual
//   server behavior files are responsible for inserting the code on the
//   page, so this function just returns the empty string.
//
// ARGUMENTS:
//   none
//
// RETURNS:
//   string - empty string to indicate that nothing should be inserted
//--------------------------------------------------------------------

//--------------------------------------------------------------------
// FUNCTION:
//   getSetupSteps
//
// DESCRIPTION:
//   Returns an array of steps to be displayed in an instructions
//   dialog.  The first element of the array is the text that appears
//   above the list.  The remaining elements are the steps, which will
//   be rendered in a numbered list.
//
//   The steps are each HTML, which may contain JavaScript event
//   handlers.  The event handlers can either be a JavaScript script
//   or an "event:KeyWord" syntax.  If the latter is used, then the
//   handler for KeyWord is implemented internally in the Dreamweaver
//   executable.
//
// ARGUMENTS:
//   none
//
// RETURNS:
//   the array described above
//--------------------------------------------------------------------

//--------------------------------------------------------------------
// FUNCTION:
//   setupStepsCompleted
//
// DESCRIPTION:
//   Returns the number of steps (in the list of steps returned from
//   getSetupSteps) that have already been completed.  This number is
//   used to determine how many steps will have a check mark next to
//   them.
//
// ARGUMENTS:
//   none
//
// RETURNS:
//   An integer - the number of check marks to be displayed, or -1
//   if all steps have been completed.
//--------------------------------------------------------------------

//
// DESCRIPTION:
//   The function returns true if this object can be inserted in the
//   current document.  This function, and the functions it calls should
//   display the necessary error messages.
//
// ARGUMENTS:
//   sbFileName - string - the file name of the server behavior file
//     which implements this object
//
// RETURNS:
//   boolean - true if the dialog should be displayed, or false otherwise
