  • Add frequently_lt_nhds and frequently_gt_nhds.
  • Move some lemmas from Topology/Order/Basic to Topology/Algebra/Order/LeftRight.
  • Relax TC assumptions in Filter.Eventually.exists_lt (and *_gt).
    New versions assume NeBot (𝓝[<] a) and NeBot (𝓝[>] a),
    so the latter one can be applied, e.g., to ((a : ℝβ‰₯0) : ℝβ‰₯0∞).
