Valuation.IsRankOneDiscrete

Given a linearly ordered commutative group with zero Γ such that Γˣ is nontrivial cyclic, a valuation v : A → Γ on a ring A is discrete, if genLTOne Γˣ belongs to the image. Note that the latter is equivalent to asking that 1 : ℤ belongs to the image of the corresponding additive valuation.
