The subspace distance is a special distance that indicates the dissimilarity between subspaces of equal dimensionality. The subspace distance between two points is a pair consisting of the distance between the two subspaces spanned by the strong eigenvectors of the two points and the affine distance between the two subspaces. @author Elke Achtert
