[in]	elt_size	size associated with each element
[in]	n_elts	number of elements to be indexed
[in]	elts	array of elements
[in]	weight	optional weight of each element, or NULL
[in]	order	ordering array
[out]	dest_rank_id	destination rank id (size: n_elts)
[in]	s_to_elt	coordinate to element conversion function
[in]	compare	comparison function
[in]	f_input	optional input to s_to_elt and compare, or NULL
[in]	comm	MPI communicator on which we build the global index
