+/**
+ * Notation tool base class.
+ *
+ * A NotationTool represents one of the items on the notation toolbars
+ * (notes, rests, clefs, eraser, etc...). It handle mouse click events
+ * for the NotationView ('State' design pattern).
+ *
+ * A NotationTool can have a menu, normally activated through a right
+ * mouse button click. This menu is defined in an XML file, see
+ * NoteInserter and noteinserter.rc for an example.
+ *
+ * This class is a "semi-singleton", that is, only one instance per
+ * NotationView window is created. This is because menu creation is
+ * slow, and the fact that a tool can trigger the setting of another
+ * tool through a menu choice). This is maintained with the
+ * NotationToolBox class This means we can't rely on the ctor/dtor to
+ * perform setting up, like mouse cursor changes for instance. Use the
+ * ready() and stow() method for this.
+ *
+ * @see NotationView#setTool()
