 * Page Description:
 * Display a timebar view of a single day.
 *
 * Input Parameters:
 * id (*) - specify view id in webcal_view table
 * date - specify the starting date of the view.
 *   If not specified, current date will be used.
 * friendly - if set to 1, then page does not include links or
 *   trailer navigation.
 * (*) required field
 *
 * Security:
 * Must have "allow view others" enabled ($allow_view_other) in
 *   System Settings unless the user is an admin user ($is_admin).
 * If the view is not global, the user must be owner of the view.
 * If the view is global, then and user_sees_only_his_groups is
 * enabled, then we remove users not in this user's groups
 * (except for nonuser calendars... which we allow regardless of group).
