	<h4>Rank of a dataset</h4>
	<p>Where a <code>rank</code> is required it must be equal to the length of the <code>dim</code>, <code>max</code>
	&amp; <code>chunk</code> parameters, if they are given, and should be:</p>
	<ul>
		<li><code>0</code>, for scalar data</li>
		<li><code>1</code>, for vector data</li>
		<li><code>2</code>, for matrix data</li>
		<li><code>3</code>, for volume data</li>
		<li>etc...</li>
	</ul>
	<p>The maximum rank is defined by the HDF5 library, a negative rank makes no sense and will often be treated as an error.</p>
