/**
 * @class	Calendarbook
 * @brief	This class manages calendar data such as events, to-dos, and calendars.
 *
 * @since	2.0
 *
 * @final	This class is not intended for extension.
 *
 * The %Calendarbook class manages calendar data such as events, to-dos, and calendars.
 * The calendar book is a centralized database that is used by multiple applications to store events and to-do information.
 * A calendar book represents the methods to read, add, remove, and update the events, to-do lists, and calendars stored in the device.
 * The users must be notified of changes in the calendar book as multiple applications can share, change, or remove the data.
 *
 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/social/calendarbook_namespace.htm">Calendar book</a>.
 *
 * The following example demonstrates how to use the %Calendarbook class to add calendarbook event.
