users can now filter items based on their container type. bug exists that page needs to be refreshed to work with categories angular above
made api for items to display in categories index. items currently still being displayed using erb
api works to list out items in list. delete button not working. need to add filter so only items for that group show up
API now works so that items only list out if they belong to the group of the current page the user is viewing
added shopping list type to view using angular
