   5   * Page Description:
   6   * This page will display the month "view" with all users's events
   7   * on the same calendar.  (The other month "view" displays each user
   8   * calendar in a separate column, side-by-side.)  This view gives you
   9   * the same effect as enabling layers, but with layers you can only
  10   * have one configuration of users.
  11   *
  12   * Input Parameters:
  13   * id (*) - specify view id in webcal_view table
  14   * date - specify the starting date of the view.
  15   *   If not specified, current date will be used.
  16   * friendly - if set to 1, then page does not include links or
  17   *   trailer navigation.
  18   * (*) required field
  19   *
  20   * Security:
  21   * Must have "allow view others" enabled ($allow_view_other) in
  22   *   System Settings unless the user is an admin user ($is_admin).
  23   * If the view is not global, the user must be owner of the view.
  24   * If the view is global, then and user_sees_only_his_groups is
  25   * enabled, then we remove users not in this user's groups
  26   * (except for nonuser calendars... which we allow regardless of group).
