/**

 * <p>

 * This interface acts as window manager. It is the place to create

 * new windows, close existing ones or modify their properties

 * (size, position, etc).

 * </p>

 * <p>

 * Any class extending from JPanel and implementing the {@link IWindow}

 * interface may become an Andami window. Andami will create a real

 * window (normally a JInternalFrame) and put the JPanel inside the

 * real window. In order to differentiate the contents (panels

 * extending JPanel and implementing IWindow) from the real window

 * (normally JInternalFrames or JDialogs), we will use

 * <i>window</i> to refer to the contents and <i>frame</i>

 * to refer to the real window.

 * </p>

 * <p>

 * This class is implemented by the Andami Skin (currently libCorePlugin),

 * which will decide the final implementation of frames. A different frame

 * implementation could be used by switching the Skin.
