wavelet transforms. Classes that implement forward wavelet transfoms should
implement this interface.</p>
<pre><code>       &lt;p&gt;This class does not define the methods to transfer data, just the
       specifics to forward wavelet transform. Different data transfer methods are 
       evisageable for different transforms.&lt;/p&gt;
