 *
 * Page Description:
 * This page will display a timebar for a week or month as specified by timeb.
 *
 * 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.
 * timeb     - 1 = week, else month
 * (*) 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).
