This module gets stock quotes from Yahoo! Finance. The getonequote
function will return a quote for a single stock symbol, while the
getquote function will return a quote for each of the stock symbols
passed to it.  getcustomquote allows to specify a format other than
the default to take advantage of the extended range of available
information.
