This will allow Loogle to find pieces of the standard library which mathlib currently does not use, like the date and time API.

  • The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
  • The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

  Use the lemma we already added.
  Minor reordering.
  This is true even for the trivial ring.
  Also add the lt versions and the other inj lemma.
  Also add the basis ne versions.
  This seems also like it should be simp.
  Back to sorry free.
  And the natDegree version.
