Don't include <iostream> and "using" declarations in header files

<iostream> sucks in expensive initialization of the standard streams
and isn't appropriate in a header file. Use <istream> and <ostream>
instead.

using declarations should never appear at global scope in a header
file; source files get to decide what they want to use in their
namespace.
