Add Redux Cart Logic

[gabriel-flynn]

• We want the id field in the cart reducer/store to be a set instead of an array
  • Add to cart should add the id to the set
  • Remove from cart should remove the id from the set
• We want to create an action that looks at the ids in our cart store/reducer and then filter out the data in our table (the tableData field) to match the ids that are contained in the set
