Squashed commit of the following:

Fixed up package.rb

    Updated to RSPEC3 syntax per Seth, cleaned up a bit.

    Per @sethvargo: "Can you refactor this to use the RSpec 3 matchers and new syntax we are moving toward?

    A few things:

    Do not start it blocks with "should". Declare instead
    Don't use should prefix. Use expect() syntax instead
    Follow this kind of pattern for testing a resource matcher"
