+ * CTimestampBehavior will automatically fill date and time related atributes when the active record
+ * is created and/or upadated.
+ * You may specify an active record model to use this behavior like so:
+ * <pre>
+ * public function behaviors(){
+ * 	return array(
+ * 		'CTimestampBehavior' => array(
+ * 			'class' => 'zii.behaviors.CTimestampBehavior',
+ * 			'createAttribute' => 'create_time_attribute',
+ * 			'updateAttribute' => 'update_time_attribute',
+ * 		)
+ * 	);
+ * }
+ * </pre>
+ * The {@link createAttribute} and {@link updateAttribute} options actually default to 'create_time' and 'update_time'
+ * respectively, so it is not required that you configure them. If you do not wish CTimestampBehavior
+ * to set a timestamp for record update or creation, set the corresponding attribute option to null.
+ *
+ * By default, the update attribute is only set on record update. If you also wish it to be set on record creation,
+ * set the {@link setUpdateOnCreate} option to true.
+ *
+ * Although CTimestampBehavior attempts to figure out on it's own what value to inject into the timestamp attribute,
+ * you may specify a custom value to use instead via {@link timestampExpression}

+ * CBreadcrumbs displays a list of links indicating the position of the current page in the whole website.

+ * to return to the homepage.
+ *
+ * To use CBreadcrumbs, one usually needs to configure its {@link links} property, which specifies

+ * <pre>

+ *
+ * <pre>
+ * $this->widget('zii.widgets.CBreadcrumbs', array(

+/**
+ * CListView displays a list of data items in terms of a list.
+ *
+ * Unlike {@link CGridView} which displays the data items in a table, CListView allows one to use
+ * a view template to render each data item. As a result, CListView could generate more flexible
+ * rendering result.
+ *
+ * CListView supports both sorting and pagination of the data items. The sorting
+ * and pagination can be done in AJAX mode or normal page request. A benefit of using CListView is that
+ * when the user browser disables JavaScript, the sorting and pagination automatically degenerate
+ * to normal page requests and are still functioning as expected.
+ *
+ * CListView should be used together with a {@link IDataProvider data provider}, preferrably a
+ * {@link CActiveDataProvider}.
+ *
+ * The minimal code needed to use CListView is as follows:
+ *
+ * <pre>
+ * $dataProvider=new CActiveDataProvider('Post');
+ *
+ * $this->widget('zii.widgets.CListView', array(
+ *     'dataProvider'=>$dataProvider,
+ *     'itemView'=>'_post',   // refers to the partial view named '_post'
+ *     'sortableAttributes'=>array(
+ *         'title',
+ *         'create_time'=>'Post Time',
+ *     ),
+ * ));
+ * </pre>
+ *
+ * The above code first creates a data provider for the <code>Post</code> ActiveRecord class.
+ * It then uses CListView to display every data item as returned by the data provider.
+ * The display is done via the partial view named '_post'. This partial view will be rendered
+ * once for every data item. In the view, one can access the current data item via variable <code>$data</code>.
+ * For more details, see {@link itemView}.
+ *
+ * In order to support sorting, one has to specify the {@link sortableAttributes} property.
+ * By doing so, a list of hyperlinks that can sort the data will be displayed.
+ *

+/**
+ * CGridView displays a list of data items in terms of a table.
+ *
+ * Each row of the table represents the data of a single data item, and a column usually represents
+ * an attribute of the item (some columns may correspond to complex expression of attributes or static text).
+ *
+ * CGridView supports both sorting and pagination of the data items. The sorting
+ * and pagination can be done in AJAX mode or normal page request. A benefit of using CGridView is that
+ * when the user browser disables JavaScript, the sorting and pagination automatically degenerate
+ * to normal page requests and are still functioning as expected.
+ *
+ * CGridView should be used together with a {@link IDataProvider data provider}, preferrably a
+ * {@link CActiveDataProvider}.
+ *
+ * The minimal code needed to use CGridView is as follows:
+ *
+ * <pre>
+ * $dataProvider=new CActiveDataProvider('Post');
+ *
+ * $this->widget('zii.widgets.grid.CGridView', array(
+ *     'dataProvider'=>$dataProvider,
+ * ));
+ * </pre>
+ *
+ * The above code first creates a data provider for the <code>Post</code> ActiveRecord class.
+ * It then uses CGridView to display every attribute in every <code>Post</code> instance.
+ * The displayed table is equiped with sorting and pagination functionality.
+ *
+ * In order to selectively display attributes with different formats, we may configure the
+ * {@link CGridView::columns} property. For example, we may specify only the <code>title</code>
+ * and <code>create_time</code> attributes to be displayed, and the <code>create_time</code>
+ * should be properly formatted to show as a time. We may also display the attributes of the related
+ * objects using the dot-syntax as shown below:
+ *
+ * <pre>
+ * $this->widget('zii.widgets.grid.CGridView', array(
+ *     'dataProvider'=>$dataProvider,
+ *     'columns'=>array(
+ *         'title',          // display the 'title' attribute
+ *         'category.name',  // display the 'name' attribute of the 'category' relation
