calculate gallons from price and cost
goals:
ease data entry by allowing more values to be entered while waiting for tank to fill, and less after tank is full when rushing to leave station. example: enter odometer and fuel price...when tank is full, just need to enter 1 value (total cost) - gallons would be calculated from price and cost. otherwise, enter odometer, then wait for full tank and need to enter gallons and cost.
display calculated fuel price during data entry - currently need to go to log to verify that it is correct
flexibility - enter what you want and rest will be calculated
