Migrate form fields to a separate file so that they can be used by "edit" once that action is generated.
Revise previous app to incorporate new lessons learned in class

+ Create seed data to test that actions are working

+ Create bookmark model to validate that a title and a url are present. More validations to be added later.

+ Add @bookmarks array to index - defined in the bookmarks_controller
+ Add code block to show all the bookmark urls and titles in an unordered list.

+ Define "new" method in bookmarks_controller

+ Drop bookmark_controller and create new index.html.erb in bookmarks view (pluralization confusion when initially creating the controller)

+ Update root to reflect that index now resides within bookmarks (with an s)

+ add edit.html.erb
+ add show.html.erb

+ change title in views/layouts/application.html.erb to Bookmarkr
