ExchangePlatform class

The ExchangePlatform allows you to register a set of ExchangeRate which you can then use to do currency conversions.

We allow multiple ExchangePlatforms to exist to reflect the fact that there multiple exchanges around the world.

To use an ExchangePlatform call register for each exchange rate. If you only provide an exchange rate in one direction (AUD -> USD) then it will calculate the inverse exchange rate if required. In the real world you will probably need to provide exchange rates in both directions as they are rarely the recipricol of each other.
