- Improve the testing of the Python Cookbook
    - Create a recipe to test virtualenv
      - Created test_virtualenv.rb

    + Test scenario will verify that bin/activate exists and the virtualenv that is to be destroyed; is.
    - Create a recipe to exert virtualenv and the pip provider
      - Created test_exert.rb
