  /**
   * Adds a raster layer to the setup.

   * <p>This method configures a raster layer with the name <code>qName.getLocalPart()</code>. A
   * coverage store is created (if it doesn't already exist) with the same name. The workspace of
   * the resulting store and layer is determined by <code>qName.getPrefix()</code>.
   *
   * <p>The <tt>filename</tt> parameter defines the raster file to be loaded from the classpath and
   * copied into the data directory. The <tt>scope</tt> is used as the class from which to load the
   * file from.
   *
   * <p>In the case of adding a zipped archive that contains multiple file the <tt>filename</tt>
   * paramter should have a ".zip" extension and the <tt>extension</tt> parameter must define the
   * extension of the main raster file. The parameter is not necessary and may be null if the
   * <tt>filename</tt> does not refer to a zip file.
   *
   * <p>The <tt>props</tt> parameter is used to define custom properties for the layer. See the
   * {@link LayerProperty} class for supported properties.
   *
   * @param qName The name of the raster layer.
   * @param filename The name of the file containing the raster, to be loaded from the classpath.
   * @param extension The file extension (without a ".") of the main raster file. This parameter my
   *     be <code>null</code> only if <tt>filename</tt> does not refer to a zip file.
   * @param props Custom properties to assign to the created raster layer.
