/**
 * EShellViewClass:
 * @parent_class:	The parent class structure.
 * @label:		The initial value for the switcher action's
 *			#GtkAction:label property.  See
 *			e_shell_view_get_action().
 * @icon_name:		The initial value for the switcher action's
 *			#GtkAction:icon-name property.  See
 *			e_shell_view_get_action().
 * @ui_definition:	Base name of the UI definintion file to add
 *			when the shell view is activated.
 * @ui_manager_id:	The #GtkUIManager ID for #EPluginUI.  Plugins
 *			should use to this ID in their "eplug" files to
 *			add menu and toolbar items to the shell view.
 * @search_options:	Widget path in the UI definition to the search
 *			options popup menu.  The menu gets shown when the
 *			user clicks the "find" icon in the search entry.
 * @search_rules:	Base name of the XML file containing predefined
 *			search rules for this shell view.  The XML files
 *			are usually named something like <filename>
 *			<emphasis>view</emphasis>types.xml</filename>.
 * @view_collection:	A unique #GalViewCollection instance is created
 *			for each subclass and shared across all instances
 *			of that subclass.  That much is done automatically
 *			for subclasses, but subclasses are still responsible
 *			for adding the appropriate #GalView factories to the
 *			view collection.
 * @new_shell_content:	Factory method for the shell view's #EShellContent.
 *			See e_shell_view_get_shell_content().
 * @new_shell_sidebar:	Factory method for the shell view's #EShellSidebar.
 *			See e_shell_view_get_shell_sidebar().
 * @new_shell_taskbar:	Factory method for the shell view's #EShellTaskbar.
 *			See e_shell_view_get_shell_taskbar().
 * @toggled:		Class method for the #EShellView::toggled signal.
 *			Subclasses should rarely need to override the
 *			default behavior.
 * @update_actions:	Class method for the #EShellView::update_actions
 *			signal.  There is no default behavior; subclasses
 *			should override this.
 *
 * #EShellViewClass contains a number of important settings for subclasses.
