class_docstr: Create and store a set of contour lines or filled regions for
  a triangular grid.
  
  User-callable method: clabel
  
  Useful attributes:
    ax:
      the axes object in which the contours are drawn
    collections:
      a silent_list of LineCollections or PolyCollections
    levels:
      contour levels
    layers:
      same as levels for line contours; half-way between
      levels for filled contours.  See _process_colors method.

docstr: Draw triangular grid contour lines or filled regions,
  depending on whether keyword arg 'filled' is False
  (default) or True.
  
  The first argument of the initializer must be an axes
  object.  The remaining arguments and keyword arguments
  are described in the docstring of `tricontour`.
