<p>The labels of box, circle, database, icon and text nodes may have different margin values.
Top, right, bottom and left margins may be different for each node.</p>
<p>Setting the margin value in the network's nodes property sets it as the default.</p>
<p>Setting a the value to a number uses that number for the margins. If the value is an object, a different value for each margin will be set.</p>
<p>Note that negative values appropriately push labels outside the node.
