notebook example for transfering code from pure pandas to dask

Hi,
I'm writing a notebook example to highlight some key differences between pandas and dask. Are you interested in such a PR?
If so i have currently the following topics - (are there any additional topics that I should include?) :
1. Dask does not update - thus no "inplace=True": (e.g. rename, reset_index, dropna,)
2. reading/saving dataframes (with *)
3. some gotcha's with index
4. dd.Aggregatoin vs groupby.apply
