// Sorts a set of N coplanar vectors in a ccw order, and returns their order.
// Optionally it also returns a copy of the ordered vector set, or the indices,
// in the original unordered set, of the vectors in the ordered set (called here
// the "inverse" set of indices).
// Inputs:
// P 1 by 3N row vector of the vectors to be sorted, stacked horizontally
// N #1 by 3 normal of the plane where the vectors lie
// Output:
// order N by 1 order of the vectors (indices of the unordered vectors into
// the ordered vector set)
// sorted 1 by 3N row vector of the ordered vectors, stacked horizontally
// inv_order N by 1 "inverse" order of the vectors (the indices of the ordered
// vectors into the unordered vector set)
