Classes are declared using "struct", not "class" because the default

natural order without explicitly specifying any access mode at the begin
of the definition.
First are public constructors and destructor, then public member functions.
After that we list protected member varibables and functions. If needed,
private implemenation varibales and functions are positioned at the end.
