[svn-r26268] Added VDS example.

I ran bin/reconfigure on jam and it modified test/Makefile.in. May be Neil fixed Makefile.am,
but didn't run reconfigure?

Tested on jam.

/************************************************************
This example illustrates the concept of the virtual dataset.
The program creates three 1-dim source datasets and writes
data to them. Then it creates 2-dim virtual dataset and
maps the first three rows of the virtual dataset to the data
in the source datasets. Elements of a row are mapped to all
elements of the corresponding source dataset.
The fourth row is not mapped and will be filled with the fill
values when virtual dataset is read back.
The program closes all datasets, and then reopens the virtual
dataset, and finds and prints its creation properties.
Then it reads the values.
This file is intended for use with HDF5 Library version 1.10
