  21  * Contains address clipboard objects and related functions. The address
  22  * clipboard is implemented as a linked list of AddrSelectItem objects.
  23  * The address clipboard offers two groups of functions:
  24  *
  25  * a) Cut, copy and paste of address item objects (ItemFolder, ItemGroup,
  26  *    ItemPerson) into a folder. With this method, we can paste ItemPerson
  27  *    objects but not unattached ItemEMail objects into a folder. ItemEMail
  28  *    objects are owned by an ItemPerson object. Any ItemEMail objects that
  29  *    appear in the clipboard are ignored. If an ItemPerson object is found,
  30  *    the ItemPerson *and* ItemEMail objects that it owns are pasted.
  31  *
  32  * b) Copy and paste of ItemEMail address objects only into (below)
  33  *    ItemPerson objects. All ItemEMail objects which are owned by
  34  *    ItemPerson and referenced by ItemGroup objects are pasted. Any
  35  *    ItemFolder objects in the clipboard, and any objects owned by
  36  *    ItemFolder objects are ignored.
  37  *
  38  * Objects are inserted to the clipboard by copying (cloning)
  39  * AddrSelectItem objects from the address books selection list to the
  40  * clipboard's internal selection list. The clipboard makes use of the
  41  * object id's and address cache id's to access objects contained in
  42  * the address cache. If the referenced object is not found, it is
  43  * ignored. This eliminates the need to delete pointers in multiple
  44  * linked lists when an address object is deleted.
