  //! \brief Base class for user defined locators 
  /*!
  
    MPxLocatorNode allows the creation of user-defined locators.  A
    locator is a DAG shaped that is drawn on the screen, but that has is
    not rendered.  Locators are full dependency nodes and can have
    attributes and a compute method.
  
    To create a locator, derive off of this class and override the draw method.
    The draw method can be overridden to draw custom geometry using standard
    OpenGL calls.  The other methods of the parent class MPxNode may also
    be overridden to perform dependency node capabilities as well.
