Add an action menu to each Animal in the list to edit or delete it

[wesleyneal346]

As a user, I want the ability to edit or delete an Animal from the list. Editing should allow me to edit the data about the animal and persist the change to the server. Selecting the Delete option should verify the intent to delete: If I select "No" nothing happens and the original list is re-displayed; If I select "Yes," the animal is removed from the list and persisted to the json server.
