*
* 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).
