Using Separate Files
•Member functions can be defined as inline in the same file as the class's interface using the inline keyword or defined in a separate file.
•When we define the member functions of our class templates in a separate implementation file, we define the class' interface in a header file in the same way that we would do for a non-template class.
•To do so requires that we define or declare our member function templates with the export keyword.
•This tells the compiler that the functions can be used in other "translation units" and may be compiled separately
