/**
 * @class   vtkCubeAxesActor
 * @brief   create a  plot of a bounding box edges -
 * used for navigation
 *
 * vtkCubeAxesActor is a composite actor that draws axes of the
 * bounding box of an input dataset. The axes include labels and titles
 * for the x-y-z axes. The algorithm selects which axes to draw based
 * on the user-defined 'fly' mode.  (STATIC is default).
 * 'STATIC' constructs axes from all edges of the bounding box.
 * 'CLOSEST_TRIAD' consists of the three axes x-y-z forming a triad that
 * lies closest to the specified camera.
 * 'FURTHEST_TRIAD' consists of the three axes x-y-z forming a triad that
 * lies furthest from the specified camera.
 * 'OUTER_EDGES' is constructed from edges that are on the "exterior" of the
 * bounding box, exterior as determined from examining outer edges of the
 * bounding box in projection (display) space.
 *
 * To use this object you must define a bounding box and the camera used
 * to render the vtkCubeAxesActor. You can optionally turn on/off labels,
 * ticks, gridlines, and set tick location, number of labels, and text to
 * use for axis-titles.  A 'corner offset' can also be set.  This allows
 * the axes to be set partially away from the actual bounding box to perhaps
 * prevent overlap of labels between the various axes.
 *
 * The Bounds instance variable (an array of six doubles) is used to determine
 * the bounding box.
