replaced matplotlib function finance.quotes_historical_yahoo() (deprecated as of matplotlib 1.4.x) with finance.quotes_historical_yahoo_ochl(), enabling the example to work for the latest version of matplotlib (1.5.0).

updated import statement to support users that are on matplotlib versions older than 1.4.x

fixed typo in import.

fixed error with method invocation.
