small fix in LABELS (when called with NULL)
Author/Maintainer info removed from DESCRIPTION
length() methods for [cg]sets are no
longer aliases for
set_cardinality() (i.e., give the number of
elements in the [cg]set).
This change has been made since
methods are expected to yield integer values only.

small bug fixes
small bug fixes
interval class for possibly infinite numeric intervals added.
fuzzy rules now accept the use of brackets in the expressions.
Missing memberships are now supported.
JSS article as vignette added.
fuzzy_pi4() generator added.
[gc]set_memberships extended to allow for filter elements and to work with tuples.
L1 and L2 dissimilarities for fuzzy multisets added.
fuzzy_pi() generator added
(fuzzy) multisets are now n-bounded (where n is the maximal multiplicity). This now allows consistent complement-building.
nu-cuts added (filters elements according to multiplicity).
fuzzy inference framework added
converters for matrices added
bug fixes in ordering function and
fuzzy function generators added
extended plotting for fuzzy sets added
several functions for memberships transformation added
performance of matching operator improved
optional universes for gsets added
support for customizable sets (cset) added
A lot of bug fixes
closure and reduction of sets added
Initial release, implementing data structures and methods for ordinary sets, generalized sets (fuzzy sets, multisets, fuzzy multisets) as well as support for fuzzy logic.
