The file 'rake/gempackagetask' is obsolete and no longer supported, according to an error message I got when I tried to run rake. Use 'rubygems/package_task' instead.
Added the pkg directory to .gitignore because it was getting created when I ran 'rake' and we should not commit it to the repository.
Remove 4-year-old test results from the repo.  That kind of thing should not be committed.
