  45 =head3 pickup_locations
  46
  47 Returns available pickup locations (Koha::Library objects) for
  48     A. a specific item
  49     B. a biblio
  50     C. none of the above, simply all libraries with pickup_location => 1
  51
  52 This method determines the pickup location by two factors:
  53     1. is the library configured as pickup location
  54     2. can a specific item / at least one of the items of a biblio be transferred
  55        into the library
  56
  57 OPTIONAL PARAMETERS:
  58     item   # Koha::Item object / itemnumber, find pickup locations for item
  59     biblio # Koha::Biblio object / biblionumber, find pickup locations for biblio
  60
  61 If no parameters are given, all libraries with pickup_location => 1 are returned.
