Title: DOC: correction of example in unstack docstring

There is an error in the example of the `unstack` docstring (http://pandas.pydata.org/pandas-docs/dev/generated/pandas.DataFrame.unstack.html ):
```
>>> df = s.unstack(level=0)
>>> df
one two
a 1. 2.
b 3. 4
```
should be
```
one two
a 1. 3.
b 2. 4
```

So this PR fixes that, but in the same time I did some other adjustments. Mainly:
- added a "see also"
- added in the example the code to create the series, so one can run the example him/herself
