/**
 * \class INDI::PropertyView and INDI::WidgetView
 * \brief Provides decorator for Low-Level IXXXVectorProperty/IXXX
 *
 * INDI::PropertyView
 *
 * A class that will allow a easy transition to the new widget handling interface (future).
 * - Use PropertyView<IText>   instead of ITextVectorProperty
 * - Use PropertyView<INumber> instead of INumberVectorProperty
 * - Use PropertyView<ISwitch> instead of ISwitchVectorProperty
 * - Use PropertyView<ILight>  instead of ILightVectorProperty
 * - Use PropertyView<IBLOB>   instead of IBLOBVectorProperty
 *
 * The PropertyView<IXXX> class is compatible with low-level IXXXVectorProperty structures.
 *
 * INDI::WidgetView
 *
 * A class that will allow a easy transition to the new widget handling interface (future).
 * - Use WidgetView<IText>   instead of IText
 * - Use WidgetView<INumber> instead of INumber
 * - Use WidgetView<ISwitch> instead of ISwitch
 * - Use WidgetView<ILight>  instead of ILight
 * - Use WidgetView<IBLOB>   instead of IBLOB
 *
 * The WidgetView<IXXX> class is compatible with low-level IXXX structures.
