// AiksaurusGTK_strlist class
// --------------------------
//   This is a wrapper for the GList class which provides string copying
//   features so that you can add strings and store them directly in the list
//   with a minimum of fuss.
//   In other words, when you push_back() or push_front() strings to this list,
//   a copy of the string will be put in the list.  This makes it much easier 
//   to reuse pointers and so forth, and you don't have to remember to delete 
//   the strings you've added because the destructor does it for you.
