Routine Description: 
 
    This routine translates the given FsFilter Operation code into a printable 
    string which is returned.   
 
Arguments: 
 
    FsFilterOperation - the FsFilter operation code to translate 
    FsFilterOperationName - a buffer at least OPERATION_NAME_BUFFER_SIZE 
                characters long that receives the name. 
 
Return Value: 
 
    None.
