//! This class defines a Windows NT window class. <br>
//!          A window in Windows NT is always created based on a <br>
//!          window class. The window class identifies the window <br>
//!          procedure that processes messages to the window. Each <br>
//!          window class has unique name ( character string ). More <br>
//!          than one window can be created based on a single window <br>
//!          class. For example, all button windows in Windows NT <br>
//!          are created based on the same window class. The window <br>
//!          class defines the window procedure and some other <br>
//!          characteristics ( background, mouse cursor shape etc. ) <br>
//!          of the windows that are created based on that class. <br>
//!          When we create a window, we define additional <br>
//!          characteristics of the window that are unique to that <br>
//!          window. So, we have to create and register window <br>
//!          class before creation of any window. Of course, it's possible <br>
//!          to create a new window class for each window inside <br>
//!          the Window class and do not use the WClass at all. <br>
//!          We implemented this class for sake of flexibility of <br>
//!          event processing. <br>
