DOC: 10 Minutes to Pandas - docs missing 'pd.' in example code
In the 10 Minutes to Pandas documentation (http://pandas.pydata.org/pandas-docs/stable/10min.html) there are several places where the sample code shows

'Series', 'date_range' or other Pandas methods are missing 'pd.'. 

If you evaluate the code examples, you get this error:

```
NameError: name 'Series' is not defined
```

NOTE: This error occurs when you're evaluating sample code in the docs.
