Financial stock market quotes grabber & caching class

This class allows you to grab financial stock market quotes from Yahoo finance's CSV file. This class doesn't provide a graphical interface to display the values, but returns them as an array. The big advantage is that you may include stock quotes nicely in your website (a.e in tickers), without having to use 'cheap looking' remote hosted JavaScript tickers. For high frequented sites, a cache functionality is included to prevent this script from transfering the quotes every time you access a page. It has multiple symbol support and does non-existing symbol error checking.
