/**
* @class vtkWidgetCallbackMapper
* @brief map widget events into callbacks
*
* vtkWidgetCallbackMapper maps widget events (defined in vtkWidgetEvent.h)
* into static class methods, and provides facilities to invoke the methods.
* This class is templated and meant to be used as an internal helper class
* by the widget classes. The class works in combination with the class
* vtkWidgetEventTranslator, which translates VTK events into widget events.
