Changes for version 3.0000
- Added tests (for ->count, ->sum, ->sumsq, ->min, ->max)
- Localized the scope of $stat and other variables in t/descr.t
- Got rid of AUTOLOAD in favour of individual accessors.
- Converted many direct member accesses to the accessors.
- Added ->frequency_distribution_ref() which deprecates frequency_distribution().
- Some refactoring of the lib/Statistics/Descriptive.pm module (without breaking the documented API).
- Statistics::Descriptive - Module of basic descriptive statistical functions.
