Subject: [PATCH] Add files via upload

Modified day 4 to allow bot to a) get data from an sqlite database and to respond to compound questions which return multiple "tool requests"
Simple case:  "How much is ticket to Rome?" - will respond with a price for an economy ticket from database.
Compound case: "What about Business and First Class? - will respond with prices for each.
