Corrected a few mistakes, tested the new 'Dao.String.b64Encode' and 'Dao.String.b64Decode' functions. It works perfectly, it's output is indentical to that of the Linux GNU "base64" program, and can decode data generated by "base64".
Revamped the pretty-printer. It is really very specific to my own personal coding style, that is the only benedit to rolling my own.
Re-arranged some comments.
Added the "Dao.PPrint.pList_" function, it has come in handy for several of the 'Dao.PPrint.PPrintable' instance declarations in "Dao.Object.Show".
Finished implementing the rough outline of the 'PPrintable' instances for all possible 'Dao.Object.Object' data types. Now I have enough to begin testing the new pretty-printer.
