// using_std_string.h: Allows building this code in environments where
//                     global string (::string) exists.
//
// The problem:
// -------------
// Let's say you want to build this code in an environment where a global
// string type is defined (i.e. ::string).  Now, let's suppose that ::string
// is different that std::string and you'd like to have the option to easily
// choose between the two string types.  Ideally you'd like to control which
// string type is chosen by simply #defining an identifier.
//
// The solution:
// -------------
// #define HAS_GLOBAL_STRING somewhere in a global header file and then
// globally replace std::string with string.  Then include this header
// file everywhere where string is used.  If you want to revert back to
// using std::string, simply remove the #define (HAS_GLOBAL_STRING).
