class_docstr: A class for wälder, that are phylogenetic forests, elements of the Wald Space.
  
  Parameters
  ----------
  topology : Topology
      The structure of the forest.
  weights : array-like
      The edge weights, array of floats between 0 and 1, with m entries, where m is
      the total number of splits/edges in the structure ``top``.

docstr: Return the fancy printable string representation of the wald.
  
  This string representation does NOT require that one can retrieve all necessary
  information from the string, but this string representation is required to be
  readable by a human.
  
  Returns
  -------
  string_of_wald : str
      Return the fancy readable string representation of the wald.
