dependency injection example

[PythonCHB]

In the multiple inheritance module, it says:

""" Super() is the right way to do dependency injection.

https://en.wikipedia.org/wiki/Dependency_injection """

This is a pretty abstract concept, particularly for newbies -- an example would be really helpful.

Or just leave it out, and focus more on the mechanics, which is what they need now.

leave it out.....

I commented that bit out in the notes in MultipleInheritance.rst Maybe want to add it back in when if/when we update.

we don't need this -- just extra complication at this point.
