Change Node stream operator to use const Node

[GoogleCodeExporter]

I have a function that aceppts a const Element, and I want to stream it to
an std::ostringstream.  But I can't.  

Can we change the stream output operator to this:

friend std::ostream& operator <<( std::ostream& out, const Node& base )
{
  out << *base.GetTiXmlPointer();
  return out;
}
