it's not really a big issue, but the kosher approach would be to prefix
all STL stuff with std:: in the headers, and 'using namespace std' in
the source files. Otherwise including the headers could cause naming
conflicts to someone who's not using the stl and wants to use the same
identifiers. The fact that most C++ programs use it makes it a small
issue, but it's sensible programming practice nevertheless.
