/**
 * UI for calendar
 *
 * Calendar has multiple different views of the same data.  All the templates
 * for the different view are loaded at the start, then the view objects
 * in CalendarApp.views are used to manage the different views.
 * update_state() is used to change the state between the different views, as
 * well as adjust only a single part of the state while keeping the rest unchanged.
 *
 * The event widgets (and the nextmatch) get the data from egw.data, and they
 * register update callbacks to automatically update when the data changes.  This
 * means that when we update something on the server, to update the UI we just need
 * to send back the new data and if the event widget still exists it will update
 * itself.  See calendar_uiforms->ajax_status().
 *
 * To reduce server calls, we also keep a map of day => event IDs.  This allows
 * us to quickly change views (week to day, for example) without requesting additional
 * data from the server.  We keep that map as long as only the date (and a few
 * others - see update_state()) changes.  If user or any of the other filters are
 * changed, we discard the daywise cache and ask the server for the filtered events.
 *
