The largest of polynomially many values

An algorithm reading a formula has to know how many variables it mentions, which is the largest index any literal names. More generally: given a rule that computes a value for each index, take the largest over a bounded range.

The maximum moved to Complexitylib.Classes.P.Range, which computes it as a count and keeps its old names: maxOver, le_maxOver, maxOver_le, maxOver_attained, maxFn, maxFn_mem_FP and maxFn_eq. This module re-exports it, together with its former imports, so that its importers see the same names as before.
