Added additional picker view to the trip purpose view along with its data source and delegate (let those be a separate file since the view is already controlling another picker view). Attempted to make the record view look nice for tablets. Changed the colors (temporarily?) for the trip purpose page for readability.
Fixed issue with the custom picker deleting the selected option. Keyboard is now dismissed when the background is tapped. Made all cost related fields conditional (visible) on whether the user sets them to be true. Added a bit of extra padding to the scrollview.
