class_docstr: An Axes positioning class.
  
  The divider is initialized with lists of horizontal and vertical sizes
  (:mod:`mpl_toolkits.axes_grid1.axes_size`) based on which a given
  rectangular area will be divided.
  
  The `new_locator` method then creates a callable object
  that can be used as the *axes_locator* of the axes.
