[boost] Added stream adaptors and array-based streams to sandbox

In the Boost CVS sandbox, I added:

<boost/io/stream_wrapping.hpp>
    A systematic way to stream types from a new streambuf type

<boost/io/array_stream.hpp>
    A streambuf that uses an internal array for its work.
    Not very useful, meant more as an application of stream-wrapping

BOOST_ROOT/libs/io/array_stream_test.cpp
    A simple demonstration of the above two headers
    Needs much improvement, help?

<boost/io_fwd.hpp>
    Updated for the two headers listed

I realized that we make new I/O source/sink types by creating a new
streambuf type.  Then we write attached streams that use that streambuf.
The standard library works this way.  I hope my classes can automate the
process somewhat.

Opinions?
