Detailed Description
template<size_t d>
class gtsam::ShonanFactor< d >
ShonanFactor is a BetweenFactor that moves in SO(p), but will land on the SO(d) sub-manifold of SO(p) at the global minimum. It projects the SO(p) matrices down to a Stiefel manifold of p*d matrices.

Constructor. Note we convert to d*p-dimensional noise model. To save memory and mallocs, pass in the vectorized Lie algebra generators: G = boost::make_shared<Matrix>(SOn::VectorizedGenerators(p));
