+/* SFML::Event holds all the informations about a system event that just happened.
+ *
+ * Events are retrieved using the SFML::Window#GetEvent function.
+ *
+ * A SFML::Event instance contains the type of the event (mouse moved, key pressed, window closed, ...)
+ * as well as the details about this particular event. Please note that the event parameters are 
+ * defined in a union, which means that only the member matching the type of the event will be properly
+ * filled; all other members will have undefined values and must not be read if the type of the event 
+ * doesn't match. For example, if you received a KeyPressed event, then you must read the event.Key
+ *  member, all other members such as event.MouseMove or event.Text will have undefined values.
+ *
+ * The ruby version differs from C++ in that the parameters are still stored in a union but that
+ * the values are directly accessible from the event object. If you try to access any data which
+ * would be considered undefined then a SFML::SomeKindOfException will be thrown.
+ *
+ * Usage example:
+ *
+ *  while event = window.getEvent()
+ *
+ *     # Request for closing the window
+ *     if event.type == SFML::Event::Closed
+ *       window.close
+ *
+ *     # The escape key was pressed
+ *     if ( event.type == sf::Event::KeyPressed ) && ( event.code == SFML::Key::Escape )
+ *       window.close
+ *
+ *     # The window was resized
+ *     if event.type == SFML::Event::Resized
+ *       DoSomethingWithTheNewSize(event.width, event.height);
+ *
+ *     # etc ...
+ *   end
