/** 
sl@0
    23
This class is a low-level class for bi-directionally reordering text. It 
sl@0
    24
allows the re-ordering of text using no leaving functions at all, and provides 
sl@0
    25
a finer degree of control than TBidiText. However, it should not be used 
sl@0
    26
without understanding the basics of the Unicode Bi-directional Reordering 
sl@0
    27
Algorithm.
