* $Id: view_l.php,v 1.33 2005/03/21 22:16:07 umcesrjones Exp $
*
* Page Description:
* This page will display the month "view" with all users's events
* on the same calendar. (The other month "view" displays each user
* calendar in a separate column, side-by-side.) This view gives you
* the same effect as enabling layers, but with layers you can only
* have one configuration of users.
*
* 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).
