* Version 0.6.2 released.
* ChangeLog: Updated file.
* DESCRIPTION: Updated file.
* NEWS: Updated file.
* inst/defuzz.m: Edited in response to Bug #56008 (defuzz provides inaccurate
results). The defuzz results were not inaccurate, but the bug report did
suggest an improvement. The defuzz option "centroid" was redefined using a
more efficient method (weighted average, as suggested by the poster of the
bug report), and the previous "centroid" implementation was renamed
"centroid_integral" to continue to provide the integral-based option.
Several new tests were added to the existing tests in defuzz.m, and the
documentation was updated.

to 'centroid_integral'.
