There are number of ways to do it. NumPy's C API has an iterator that
returns an axis on demand. Mine just collects an array with pointers to
the first element in each axis. The latter is more friendly to
parallelization (OpenMP or Python threads with released GIL), which is why
I wrote it, otherwise it has no advantage over NumPy's.
