#ifdef'ing the code out would break documented public APIs, so this
particular solution is not really doable.  Sorry.

Furthermore, functions for error notifications (eg. out of bounds
access) also print to the cout stream by default.

I'm open to looking at solutions which provide a different default
stream, as long as it's a C++ std::ostream.
