// The Onnx spec refers to numpy specification, used as a reference:
// https://numpy.org/doc/stable/reference/generated/numpy.unique.html
// Input : Given an array of elements : X.
// Output(s) :
// 1. Find the unique elements (Y) of input (X).
//
// There are three outputs in addition to the unique elements in Y:
// 2. the indices of the input array that give the unique values
// 3. the indices of the unique array that reconstruct the input array
// 4. the number of times each unique value comes up in the input array
// Optional Attribute: 'Sorted' = 1 for sorted; = 0 for unsorted.
// Onnx specification makes 'sorted' a default, while Numpy always sorts.
//
// Optional Attribute: 'Axis' is 'None' (default) or a valid int < rank(X).
// Negative values are allowed.
//
// Numpy has the following important note on Axis:
// ------------------------------------------------------------------
// When an axis is specified the subarrays indexed by the axis are
// sorted. This is done by making the specified axis the first
// dimension of the array (move the axis to the first dimension to
// keep the order of the other axes) and then flattening the subarrays
// in C order. The flattened subarrays are then viewed as a structured
// type with each element given a label, with the effect that we end
// up with a 1-D array of structured types that can be treated in the
// same way as any other 1-D array. The result is that the flattened
// subarrays are sorted in lexicographic order starting with the first
// element.
