+/** 
+CWsObject is the base class for the server-side objects that are visible to the client.
+
+The client refers to these objects via a handle that is passed to it by the server.
+The association between handles and CWsObject instances is stored by the TWsObject class.
+
+Derived classes must implement the CommandL() function so that it handles the requests
+the client sent.
+
+Each client session has a list of all its CWsObject instances. When creating an instance of 
+a class derived from CWsObject the NewObjL() function must be called to add the new 
+object to the list. The CWsObject destructor takes care of removing the object from the list.
