  • Define absolute continuity between measures (@mzinkevi)
  • State monotonicity of ae_measurable w.r.t. absolute continuity
  • Weaken some measurable assumptions in prod.lean to ae_measurable
  • Some docstring fixes
  • Some cleanup

I'm open to a different (shorter) name than absolutely_continuous

Is this PR really only "Haar typos" or should it get a different title?

It started out as fixing some typos, but it evolved a bit. 😄 I fixed the title.

Also, can you replace "fix" in the title with "feat"? And I am fine with absolutely_continuous.
