Notes:

• From Andrew's script - ideas on what we need to do in the database when we first add an item:
  • Store date of purchase
  • Store number of purchases for the item
  • Store next purchase date

I think the app will need to update our numberOfDays with the result of this function.

How is a purchase recorded?

• Changes to database:
  • change all three of above
  • change numberOfDays
