The Apollo spacecraft had three parts:</p>
-

-			<li><strong>Command Module</strong> with a cabin for the three astronauts which was the only part which landed back on Earth</li>
-			<li><strong>Service Module</strong> which supported the Command Module with propulsion, electrical power, oxygen and water</li>
-			<li><strong>Lunar Module</strong> for landing on the Moon.</li>
-		</ol>
-
-		<p>After being sent to the Moon by the Saturn V&#39;s upper stage, the astronauts separated the spacecraft from it and travelled for three days until they entered into lunar orbit. Armstrong and Aldrin then moved into the Lunar Module and landed in the <a href="http://en.wikipedia.org/wiki/Mare_Tranquillitatis" title="Mare Tranquillitatis">Sea of Tranquility</a>. They stayed a total of about 21 and a half hours on the lunar surface. After lifting off in the upper part of the Lunar Module and rejoining Collins in the Command Module, they returned to Earth and landed in the <a href="http://en.wikipedia.org/wiki/Pacific_Ocean" title="Pacific Ocean">Pacific Ocean</a> on July 24.</p>

-/**
- * CSS classes applied to aligned images. Useful to take control over the way
- * the images are aligned, i.e. to customize output HTML and integrate external stylesheets.
- *
- * Classes should be defined in an array of three elements, containing left, center, and right
- * alignment classes, respectively. For example:
- *
- *		config.image2_alignClasses = [ 'align-left', 'align-center', 'align-right' ];
- *
- * **Note**: Once this configuration option is set, the plugin will no longer produce inline
- * styles for alignment. It means that e.g. the following HTML will be produced:
- *
- *		<img alt="My image" class="custom-center-class" src="foo.png" />
- *
- * instead of:
- *
- *		<img alt="My image" style="float:left" src="foo.png" />
- *
- * **Note**: Once this configuration option is set, corresponding style definitions
- * must be supplied to the editor:
- *
- * * For [classic editor](#!/guide/dev_framed) it can be done by defining additional
- * styles in the {@link CKEDITOR.config#contentsCss stylesheets loaded by the editor}. The same
- * styles must be provided on the target page where the content will be loaded.
- * * For [inline editor](#!/guide/dev_inline) the styles can be defined directly
- * with `<style> ... <style>` or `<link href="..." rel="stylesheet">`, i.e. within the `<head>`
- * of the page.
- *
- * For example, considering the following configuration:
- *
- *		config.image2_alignClasses = [ 'align-left', 'align-center', 'align-right' ];
- *
- * CSS rules can be defined as follows:
- *
- *		.align-left {
- *			float: left;
- *		}
- *
- *		.align-right {
- *			float: right;
- *		}
- *
- *		.align-center {
- *			text-align: center;
- *		}
- *
- *		.align-center > figure {
- *			display: inline-block;
- *		}

-		<p>After being sent to the Moon by the Saturn V&#39;s upper stage, the astronauts separated the spacecraft from it and travelled for three days until they entered into lunar orbit. Armstrong and Aldrin then moved into the Lunar Module and landed in the <a href="http://en.wikipedia.org/wiki/Mare_Tranquillitatis" title="Mare Tranquillitatis">Sea of Tranquility</a>. They stayed a total of about 21 and a half hours on the lunar surface. After lifting off in the upper part of the Lunar Module and rejoining Collins in the Command Module, they returned to Earth and landed in the <a href="http://en.wikipedia.org/wiki/Pacific_Ocean" title="Pacific Ocean">Pacific Ocean</a> on July 24.</p>

-	/**
-	 * An instance of a widget. Together with {@link CKEDITOR.plugins.widget.repository} these
-	 * two classes constitute the core of the Widget System.
-	 *
-	 * Note that neither the repository nor the widget instances can be created by using their constructors.
-	 * A repository instance is automatically set up by the Widget plugin and is accessible under
-	 * {@link CKEDITOR.editor#widgets}, while widget instances are created and destroyed by the repository.
-	 *
-	 * To create a widget, first you need to {@link CKEDITOR.plugins.widget.repository#add register} its
-	 * {@link CKEDITOR.plugins.widget.definition definition}:
-	 *
-	 *		editor.widgets.add( 'simplebox', {
-	 *			upcast: function( element ) {
-	 *				// Defines which elements will become widgets.
-	 *				if ( element.hasClass( 'simplebox' ) )
-	 *					return true;
-	 *			},
-	 *			init: function() {
-	 *				// ...
-	 *			}
-	 *		} );
-	 *
-	 * Once the widget definition is registered, widgets will be automatically
-	 * created when loading data:
-	 *
-	 *		editor.setData( '<div class="simplebox">foo</div>', function() {
-	 *			console.log( editor.widgets.instances ); // -> An object containing one instance.
-	 *		} );
-	 *
-	 * It is also possible to create instances during runtime by using a command
-	 * (if a {@link CKEDITOR.plugins.widget.definition#template} property was defined):
-	 *
-	 *		// You can execute an automatically defined command to
-	 *		// insert a new simplebox widget or edit the one currently focused.
-	 *		editor.execCommand( 'simplebox' );
-	 *
-	 * Note: Since CKEditor 4.5 widget's `startupData` can be passed as the command argument:
-	 *
-	 *		editor.execCommand( 'simplebox', {
-	 *			startupData: {
-	 *				align: 'left'
-	 *			}
-	 *		} );
-	 *
-	 * A widget can also be created in a completely custom way:
-	 *
-	 *		var element = editor.document.createElement( 'div' );
-	 *		editor.insertElement( element );
-	 *		var widget = editor.widgets.initOn( element, 'simplebox' );
-	 *
-	 * @since 4.3
-	 * @class CKEDITOR.plugins.widget
-	 * @mixins CKEDITOR.event
-	 * @extends CKEDITOR.plugins.widget.definition
-	 * @constructor Creates an instance of the widget class. Do not use it directly, but instead initialize widgets
-	 * by using the {@link CKEDITOR.plugins.widget.repository#initOn} method or by the upcasting system.
