Altered models to create an association between list items and foods.  Additionally, I created and ran a migration to add amount to the list items model
Added numericality and presence validation for amount to list items
Fixed a few errors in several view pages where I was not invoking the name, but rather the object itself (so I would see strings with the <object> instead of its name)
Added a placeholder list items controller
revised list_items controller and list show page to both allow for the proper creation of list items and the proper display of that information.
Corrected a capitalization error in the add item to list test and add a '!' to the Successfully Created notice for creating new items
