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.
