    NAME:       SPIN_SLE_STR

    SYNOPSIS:   SPIN ITEM object which handles string

    INTERFACE:
                SPIN_SLE_STR() - constructor
                ~SPIN_SLE_STR() - destructor

		QueryContent()	  - return the current context in the window
		Update()	  - Refresh the current window's context
                SaveCurrentData() - Get the current window's context and
                                    store it in the internal variable
                QueryAccCharPos() - It will test whether the given character
                                    is the first character of the object's
                                    string set.

    PARENT:     SLE, CHANGEABLE_SPIN_ITEM

    USES:       NLS_STR

    CAVEATS:    In order to use this class, the user needs to define
                a list of strings. The identifier of the list of strings
                must be continuous.
