ANSI C++ changes revisited

[Eric Chamberland]

Hi,

just a not about the "using std::ostream"...  You should NOT do this if
it is in a header file, because any who include you header file will
have the "using std::ostream" effctive for his files...  So in all our
header files (and template files) we do simply write each method with
std::ostream instead of doing a "using std::ostream".

so you woould probably want do to :

PrintSelf(std::ostream...); // in your header file

and in you source you could do:
using std::ostream;
PrintSelf(ostream...)
{
}
or 
PrintSelf(std::ostream...)

This means code writers don't have to worry about these special types.
