- consistent use of throw () in function decl/defn.
- keep tree balanced in insert() and erase().

    http://www.cgal.org/
    http://www.cs.umd.edu/~mount/ANN/
- erase(range)
- improved copy constructor and operator= (Paul Harris)
- possibly rename all __* variables, since __* is reserved for the compiler.
