%description
S4 classes and methods to deal with fuzzy numbers. They allow for
computing any arithmetic operations (e.g., by using the Zadeh extension
principle), performing approximation of arbitrary fuzzy numbers by
trapezoidal and piecewise linear ones, preparing plots for publications,
computing possibility and necessity values for comparisons, etc.
