/**

 * <p>

 * <b>Class View</b>. This class represents the gvSIG specific internal window where the maps are

 * displayed and where the events coming from the user are captured.

 * </p>

 * <p>

 * It is composed by three main visual areas:

 * </p>

 * <ol>

 *          <li>

 *     <b>Map control</b>: the map area located in the right area of the window. It takes up

 *     the biggest part of the window.

 *   </li>

 *          <li>

 *     <b>Table of contents (TOC)</b>: is a list of layers displayed in the view. The TOC is

 *     located on the left-top corner of the View and is the place where the user can modify

 *     the order, the legends, the visibility and other properties of the layers.

 *   </li>

 *          <li>

 *     <b>Map overview</b>: is a small MapControl located in the left-bottom corner of the

 *     View where the user can put some layers which summarizes the view. It is used to make

 *     the navigation easier and faster.

 *   </li>

 * </ol>
