CodeSnip Old Code (SVN)

* Renamed UTextStreamReader unit as UStringReader and TTextStreamReader class as TStringReader. Changed TStringReader to read its data from a string instead of a stream.
* Updated using Hiliter.UPasLexer unit to use revised unit and class names.
* Updated chain of Hiliter classes that use Hiliter.UPasLexer to pass source code as a string instead of a stream. When streams were used they had to contain Unicode text, so it is safer and easier just to use strings instead.

* Renamed UAlphabet unit as UInitialLetter and completely rewrote and simplified it.
* Modified units using UInitialLetter unit as necessary re changes.
* Modified TAlphaGroupItem and TAlphaGrouping to accept any upper case Unicode character instead of just "A".."Z" and "_". Uses natural sorting so, for example "Ö" sorts between "O" and "P". Now scans all snippets to build list of initial letters.

Development branch for CodeSnip release 4.
