	 * Constructor for a new ActionSheet.
	 *
	 * @param {string} [sId] ID for the new control, generated automatically if no ID is given
	 * @param {object} [mSettings] Initial settings for the new control
	 *
	 * @class
	 * The action sheet holds a list of options from which the user can select to complete an action.
	 * <h3>Overview</h3>
	 * The options of the action sheet are represented as {@link sap.m.Button buttons} with icons.
	 * Elements in the action sheet are left-aligned. Actions should be arranged in order of importance, from top to bottom.
	 * <h3>Guidelines</h3>
	 * <ul>
	 * <li>Always display text or text and icons for the actions. Do not use icons only.</li>
	 * <li>Always provide a Cancel button on mobile phones.</li>
	 * <li>Avoid scrolling on action sheets.</li>
	 * </ul>
	 * <h3>Responsive Behavior</h3>
	 * On mobile phones the action sheet is displayed in a {@link sap.m.Dialog dialog}.
	 *
	 * On tablets and desktop the action sheet is displayed in a {@link sap.m.Popover popover}.
	 *
	 * When an action is triggered, the action sheet closes and you can display a confirmation as a {@link sap.m.MessageToast message toast}.
