[Cuis] Wrapper for file access in different Smalltalk dialects

Tue May 26 21:34:22 CDT 2015

Hi all,

I think it is nice if FileMan is on the core package repository.

FileMan for Cuis (and Squeak) has minimum dependencies to the existing
FileDirectory and DirectoryEntry. FileMan selectively uses a few
methods of them.

So we can gradually adopt FileMan interfaces and trim the
FileDirectory and DirectoryEntry's non-intuitive methods.

Another way of cleaning-up the file-related classes is to port
FileSystems to Cuis.
But since Cuis is a lightweight Smalltalk dialect, FileSystems might
be an overkill.

Best regards,
