[Dev] Notes on using super()

[Donn Denman]

I've written up some notes on using super() for the wiki:

I'm pretty new to Python, so there could be a lot of holes in the 
information presented here, but I thought it would make a good starting 
point.  I've been doing a fair bit of multiple inheritance lately, and 
found that the issues can be tricky.
