     13
     14For elements of a root lattice realization:
     151. Added method reflect which reflects across a hyperplane orthogonal
     16to a (co)root.
     172. Renamed to_positive_chamber to to_dominant_chamber, and added case checking
     18for affine root systems which prevents infinite looping. Root systems
     19that are not finite and not affine are not checked.
     203. Added method weyl_action which acts on a vector by a Weyl group element.
     214. Added method weyl_stabilizer which returns indices of simple reflections
     22fixing a weight.
