/**
* Reorders ndarray dimensions and associated strides for loop interchange.
*
* ## Notes
*
* - The returned object has the following properties:
*
* - **sh**: dimensions sorted in loop order.
* - **sx**: first input ndarray strides sorted in loop order.
* - **sy**: second input ndarray strides sorted in loop order.
* - **sz**: third input ndarray strides sorted in loop order.
* - **sw**: fourth input ndarray strides sorted in loop order.
* - **su**: fifth input ndarray strides sorted in loop order.
* - **sv**: output ndarray strides sorted in loop order.
*
* @param {NonNegativeIntegerArray} sh - array dimensions
* @param {IntegerArray} sx - first input array stride lengths
* @param {IntegerArray} sy - second input array stride lengths
* @param {IntegerArray} sz - third input array stride lengths
* @param {IntegerArray} sw - fourth input array stride lengths
* @param {IntegerArray} su - fifth input array stride lengths
* @param {IntegerArray} sv - output array stride lengths
* @returns {Object} loop interchange data
*
* @example
* var sh = [ 2, 3, 4 ];
*
* var sx = [ 12, 4, 1 ]; // row-major
* var sy = [ 24, 8, 1 ]; // row-major
* var sz = [ 12, 4, 1 ]; // row-major
* var sw = [ 24, 8, 1 ]; // row-major
* var su = [ 1, 4, 12 ]; // column-major
* var sv = [ 1, -2, 6 ]; // column-major
*
* var o = quinaryLoopOrder( sh, sx, sy, sz, sw, su, sv );
* // returns {...}
*
* var ssh = o.sh;
* // returns [ 4, 3, 2 ]
*
* var ssx = o.sx;
* // returns [ 1, 4, 12 ]
*
* var ssy = o.sy;
* // returns [ 1, 8, 24 ]
*
* var ssz = o.sz;
* // returns [ 1, 4, 12 ]
*
* var ssw = o.sw;
* // returns [ 1, 8, 24 ]
*
* var ssu = o.su;
* // returns [ 12, 4, 1 ]
*
* var ssv = o.sv;
* // returns [ 6, -2, 1 ]
