Feature request: Explain canonicalise

[incansvl]

ucum.js: 0.0.2

When user-submitted units are canonicalised the logic of how the result was achieved is sometimes obvious, sometimes not.

It would be helpful for non-developers working to "clean" historical code sets if the library was able to explain the conversion steps that were taken to transform the unit supplied in the argument to the canonicalised result.

Simple example below-

Input      Output
mV/mm      gm/C/s2

A ucum.canonicaliseExplain() function to show the transformation stages would be a useful addition.

Thanks for the comment! This library isn't actively maintained, but I'd be happy to accept a contribution along these lines.
