DESIGN.md : I believe that zero "exponents are elided" rule is a concept of exponent not base-dimension, so have modified parts where exponent rather than base dimension should apply

In order to be able to perform computations on arbitrary sets of exponents, an important
property of `units::dimension` is that its base dimensions:
- are not repeated in a list (each base dimension is provided at most once),
- are not repeated in a list (the exponent of each base dimension is provided at most once),
- are consistently ordered,
- having zero exponent are elided.
- exponents with ::num of zero are elided
