/*

    This program shows how to create, store and dereference references

    to the dataset regions.

​

    It creates a file and writes a two dimensional integer dataset

    to it. Then it creates a dataset to store region references in. It

    stores references to a hyperslab and 3 points selected (for the

    integer dataset previously created).

​

    It then reopens the references dataset, reads and dereferences the

    region references, and then reads and displays the selected hyperslab

    and selected elements data from the integer dataset.
