Release Name: 1.0.1

Notes:
* Changed license to Artistic 2.0
* Eliminated warnings that could appear with -w


Changes:
* Changed the license to Artistic 2.0.
* Fixed warnings that could occur if the @module, @name, or @instance
  variables were not set in the constructor. They are now explicitly
  set to nil if they do not have any value.
* Updates to the gemspec, including license and description.
* Renamed and performed some minor refactoring of the test and example files.
* Changed one test to use 'biostats' instead of 'flushmeter' because
  the latter does not appear to be defined in a Solaris VM.
* Added the 'example' rake task.
