Sometimes a function is best shared among a number of
different classes. Such functions can be declared either as
member functions of one class or as global functions. In
either case they can be set to be friends of other classes,
by using a friend specifier in the class that is admitting
them. Such functions can use all attributes of the class
which names them as a friend, as if they were themselves
members of that class. A friend declaration is essentially a
prototype for a member function, but instead of requiring an
implementation with the name of that class
attached by the double colon syntax, a global function or
member function of another class provides the match.
