CAD/USD Fuel Conversion

This is an app I created for myself and thought I would share. When driving through Canada, US drivers need to convert from liters to gallons AND convert the exchange rate between the dollars. This app will do that for you. You input the local CAD$ per liter. The app retrieves the current conversion rate and converts it all to USD$ per gallon. Your conversion rate may vary a bit based on the financial institution you use. However, you can override the conversion rate with one of your choosing. This app will also work for Canadian visitors to the US. You can input USD$, and it will convert to the CAD$ per liter price they are used to. If you are in Canada, the app will start in the CAD$ to USD$ mode. If in the USA, it will start in USD$ to CAD$ mode. You can change at any time. This is the first app I have done and I was an old COBOL programmer, so go easy on me.
