オブジェクトの生成

  引数パターン1
    residue : When::Coordinates::Residue
      剰余
    range   : Range(サブクラスである When::Parts::GeometricComplexでもよい)
      始点 - range.first
      終点 - range.last
    count_limit : Integer
      繰り返し回数(デフォルトは指定なし)

  引数パターン2
    residue : When::Coordinates::Residue
      剰余
    first   : When::TM::(Temporal)Position
      始点
    direction : :forward or :reverse
      :forward - 昇順
      :reverse - 降順
    count_limit : Integer
      繰り返し回数(デフォルトは指定なし)
