Summary:
The pre-amble here is misformatted at least and is hard to make sense of: https://pytorch.org/docs/master/quantization.html#prototype-fx-graph-mode-quantization
This PR is trying to make things easier to understand.
As I'm new to this please verify that my modifications remain in line with what may have been meant originally.
