Research / Drill Down

Added a Research option with drill Down option to it to aid in identifying toys.

example : To research a circus toy you would drill down starting with selecting animal drawn toys , horse drawn toys and then horse drawn circus toys. At that point you would land on a page that will hopefully contain a picture of every horse drawn circus toy type with additional reference material such as catalog pages, magazine advertisments etc. My goal will be to provide a graphic of the correct toy with correct figures where possible. Input and feedback always welcome.
