Title: Adding text to instruct the user to use IPython in tutorial.

If a user launches a regular Python session and tries to follow the tutorial, maps will not be displayed. No error or instruction on how to set things up to view the plots is returned. It would be preferable to display a warning message with direction, but adding this to the docs would be a huge help.
