Add more comments to examples

[TG-Techie]

I am a beginner in HDL and migen seems like a great option as I already know python well and it seems like migen would let me design hardware without having to learn a new language! (thank you)

however, I am having a little trouble understanding what the examples are doing. I have read https://m-labs.hk/migen/manual/fhdl.html up until clock domains but going through the examples without comments is a little tough.

If I can help add comments or provide more details as to my troubles I would be more then glad to help

Thank you, TG-Techie

like, in the docs I cannot find a listing for the memory class, I can't find a listing for the methods or inputs for hen it's being instantiated

etc
