// divisibility[d] is the largest power of two that divides the first element
// of all groups of length contiguity[d] along dimension d.
//
// For example,
//
// [[10, 11, 12, 13, 18, 19, 20, 21],
// [20, 21, 22, 23, 28, 29, 30, 31]]
//
// has divisibility [1, 2], and
//
// [[12, 16, 20, 24],
// [13, 17, 21, 25],
// [14, 18, 22, 26],
// [15, 19, 23, 27]]
//
// has divisibility [4, 1].
//
// On the other hand,
//
// [0, 1, 2, 0, 4, 5, 6, 7]
//
// has divisibility 1 because its contiguity is 1.
in second sample, contiguity should be [4, 1]， divisibility should be [1, 4], means dim0 must split 4, because dim0 is not contiguous, dim1 can split 1, because contiguous.
divisibility means a split-factor, it is misunderstand?
