Re: [boost] IO Formatting Manipulators (was Adding a generic list manipulator)

I have made several improvements:

[1] The header files can be included seperately now
[2] The examples are now linked in to the documentation
[3] The examples have more comments and the output from each is included 
after the code, e.g.

   std::cout << "list< char > = "
             << boost::io::formatlist( l )
             << '\n';

   // [results]: list< char > = [ A, B, C ]

[4] Generators have been added for boost::io::pair_output, 
boost::io::container_output and boost::io::array_output to remove the need 
to create objects outside the declerations, e.g.

   std::cout << "map< string, string > = "
             << boost::io::formatlistfn
                (
                   m,
                   boost::io::pairfmt() // use a generator:
                   .format( '(', ')' )
                )
                .format( '\n', '\0', '\n' )
                .space( false, false, false )
             << '\n' << '\n';

Examples of these have been added.

[5] A new manipulator - boost::io::formatob - has been added to support 
non-list base types, by binding an outputter to them. This allows std::pair 
and std::complex types to be formatted using my formatters (as well as any 
other object, as long as it is bound to an appropriate outputter). e.g.

   std::cout << "pair< string, int > = "
             << boost::io::formatob
                (
                   p,
                   boost::io::pairfmt()
                   .format( '(', ')', ';' )
                )
             << '\n' << '\n';

I still need to work on the documentation, and complete the generators so 
they are fully interoperable with the rest of my library.

Also, does anyone know how to use CVS to upload these files to 
boost-sandbox? I have a sourceforge account, have requested write access and 
have a cvs command-line program, but am unsure how to use it (I can't gain 
access to the files).
