In article_visitors feature - added scenario for viewing individual article
Began writing create_article feature

Changed Cucumber and Rspec tests to avoid uploading images each time the index and show tests are run.  (Articles should use default image url instead.)  Tests fails to show the image.  On LocalHost, throws error that no route matches GET "path to image"  (Though path to image seems to be correct.)

Attempted to resolve by adding "photo" as a member of "articles" in routes.rb but commented out when it failed.

Made multiple adjustments to ensure that database is cleaned before and after tests, duplicate files are not created, and running parallel tests doesn't cause errors with Paperclip.
