The marg_ostream CTOR can take a std::ostream argument.  It's located
in files/col_io directory.  I don't think there's any way to more transparent
because some method call for changing the indentation is needed.  You could
change the cout streambuf* to marg_ostreambuf* (also defined in files/col_io)
but then you'd have to call cout.rd_buf and static_cast it to marg_ostreambuf
before calling a method to change the margin.  The two files,
main.cpp and main.exp in the files/col_io directory shows a test of this.
The marg_ostream test is in the .zip file.
