Retrieve currency exchange rates from Yahoo! Finance.
The Yahoo! Finance Service
URL to fetch the AUD to USD exchange rate
http://download.finance.yahoo.com/d/quotes.csv?s=AUDUSD=X&f=nl1d1t1
Although the Yahoo! service supports multiple rates values from one request, this class does not yet support this functionality yet.
