abstract: An object-oriented package for mathematical sets, upgrading the current
  gold-standard sets. Many forms of mathematical sets are implemented, including (countably
  finite) sets, tuples, intervals (countably infinite or uncountable), and fuzzy variants.
  Wrappers extend functionality by allowing symbolic representations of complex operations
  on sets, including unions, (cartesian) products, exponentiation, and differences
  (asymmetric and symmetric).
