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.
