+Layer One: Drivers -- Hash with Driver ID's as keys and Rides (next layer) as values.
+Layer Two: Rides -- Array containing all the rides for the Driver. 
+Layer Three: Ride Specifics (Date, Cost, Riders, Rating) -- Hash with Date/Cost/Rider/Rating as the keys and the specific information for each ride as the values.
