Description

In situations where we want to run Deep Feature Synthesis for a dataset that has a many-to-many relationship we need to create an extra association entity to handle the mapping. Featuretools supports this use case, but it could be more clear to users of the library if we provided an example either in the documentation on in a demo like the ones we have on the website.

Research direction
The issue requests an example of using Deep Feature Synthesis with many to many relationships. Look at the existing documentation and demos on the Featuretools website (e.g., the demos folder in the repo). Identify where a many to many example could be added, such as a new notebook or a section in the user guide. Ensure the example uses an extra association entity as described. Check the comments for any additional context.
