Errors with nosetests-3.3  pandas.io.tests.test_yahoo.TestYahoo pandas, version b0ee363408336
I think get_quote_yahoo and get_components_yahoo in data.py need to decode the bytes returned by urllib.request.urlopen(urlStr).readlines() and urllib.urlopen(urlStr).read().strip().strip('"').split('"\r\n"') in python3.3

Also, the expected INTC values in test_get_data() in test_yahoo.py do not agree with the values Yahoo returns.  The Adj Close value for 1-18-12 is 24.28 and the calculated Ret_Index values do not agree with the values in the d array.

The tests pass after making these changes.  I have not tested the changes in python2.x
