For the 3 remaining user stories (add items, check/uncheck items, and delete items), plan out each function in pseudocode (plain language).

Add Item:

-	Need a form to capture user input for the new item
o	The name of the item
-	This information needs to be added to the STORE
-	This information needs to be placed through the render so that the list item is created and then joined together into the unordered list

Check/uncheck Item:

-	By default, list items have a property in the store set to false.
-	The checked button will toggle the property between true and false
-	When true we need to add a class to the list item the button is inside of
-	This class will add the strike through using CSS (specifically, .shopping-item__checked from index.css)

Delete Item:

-	This delete button will need to splice the STORE to remove the item that the button that was clicked lives inside
