synopsis:             Class of data structures that can be unfolded.
description:          Just as there's a Foldable class, there should also be an Unfoldable class.
                      .
                      This package provides one. Example unfolds are:
                      .
                      * Random values
                      .
                      * Enumeration of all values (depth-first or breadth-first)
                      .
                      * Convert from a list
                      .
                      Some examples can be found in the examples directory.
