Add perm * sparse, perm \ sparse, sparse * perm, and sparse / perm operations.
Nothing terribly fancy in any of this. There probably is some
mechanism for using the permutation vectors and some assign or index
method in the sparse classes, but I've never understood all the
intricacies. I'm opting for a simple implementation at the cost of
possibly duplicating some functionality.
