DESCRIPTION

       These routines perform operations on keyed lists.  See the Extended Tcl  man  page  for  a
       description of keyed lists.

   TclX_NewKeyedListObj
       Create and initialize a new keyed list object.

       Returns:
         A pointer to the object.

   TclX_KeyedListGet
         Retrieve a key value from a keyed list.

       Parameters:
         o interp - Error message will be return in result if there is an error.
         o keylPtr - Keyed list object to get key from.
         o  key  - The name of the key to extract.  Will recusively process sub-keys separated by
         `.'.
         o valueObjPtrPtr - If the key is found, a pointer to the key object
             is returned here.  NULL is returned if the key is not present.

       Returns:
         o TCL_OK - If the key value was returned.
         o TCL_BREAK - If the key was not found.
         o TCL_ERROR - If an error occurred.

   TclX_KeyedListSet
         Set a key value in keyed list object.

       Parameters:
         o interp - Error message will be return in result object.
         o keylPtr - Keyed list object to update.
         o key - The name of the key to extract.  Will recusively process  sub-key  separated  by
         `.'.
         o valueObjPtr - The value to set for the key.

       Returns:
           TCL_OK or TCL_ERROR.

   TclX_KeyedListDelete
         Delete a key value from keyed list.

       Parameters:
         o interp - Error message will be return in result if there is an error.
         o keylPtr - Keyed list object to update.
         o  key  -  The name of the key to extract.  Will recusively process sub-key separated by
         `.'.

       Returns:
         o TCL_OK - If the key was deleted.
         o TCL_BREAK - If the key was not found.
         o TCL_ERROR - If an error occurred.

   TclX_KeyedListGetKeys
         Retrieve a list of keyed list keys.

       Parameters:
         o interp - Error message will be return in result if there is an error.
         o keylPtr - Keyed list object to get key from.
         o key - The name of the key to get the sub keys for.  NULL or empty to retrieve all  top
         level keys.
         o listObjPtrPtr - List object is returned here with key as values.

       Returns:
         o TCL_OK - If the zero or more key where returned.
         o TCL_BREAK - If the key was not found.
         o TCL_ERROR - If an error occurred.
