<div class="markdown level1 summary"><p>Splits the current subband in its four subbands. It changes the status
of this element (from a leaf to a node, and sets the filters), creates
the childs and initializes them. An IllegalArgumentException is thrown
if this subband is not a leaf.</p>
<pre><code>       &lt;p&gt;It uses the initChilds() method to initialize the childs.&lt;/p&gt;
