Retrieving and displaying tips for items
Some food items have helpful tips for storage and cooking. If a food item has these tips, a button will be made visible that, when clicked, will bring users to a new activity that will display the tips. The new activity will also have a back button allowing the user to return to the previous screen. The button will be invisible by default and will only appear if there are any tips for the item (it will not appear if the tips field is null).
