A Rotor is used to transform geometric elements of the algebra.

A Rotor can be operated on by vsr::cga::Gen static methods.

They are typically created by passing in some 2-blade to a method in vsr::gen, and the result applied to any element x by calling the x.spin(<a Rotor>) method

For instance, to create a quaternionic rotation we use a Euclidean plane of rotation

  auto v = Vec(1,0,0);
  auto q = Gen::rotor( Biv(PI,0,0) );
  auto n = v.spin(q);
