Replace 'shape' with another term in README and formatting #590
Description
Commenting on #574, @macchiati said:
I think the term "shape" is confusing for many readers and may well be misleading: I stumble across a term like "implementation's shape".
It appears that "structure" is what is meant. If so, it should be replaced by that.
If this is merged, I can move this comment to the new issue for cleanup.
