=head1 NAME
C4::Breeding : module to add biblios to import_records via
the breeding/reservoir API.
=head1 SYNOPSIS
use C4::Scan;
&ImportBreeding($marcrecords,$overwrite_biblio,$filename,$z3950random,$batch_type);
C<$marcrecord> => the MARC::Record
C<$overwrite_biblio> => if set to 1 a biblio with the same ISBN will be overwritted.
if set to 0 a biblio with the same isbn will be ignored (the previous will be kept)
if set to -1 the biblio will be added anyway (more than 1 biblio with the same ISBN
possible in the breeding
C<$encoding> => USMARC
or UNIMARC. used for char_decoding.
If not present, the parameter marcflavour is used instead
C<$z3950random> => the random value created during a z3950 search result.
=head1 DESCRIPTION
ImportBreeding import MARC records in the reservoir (import_records/import_batches tables).
the records can be properly encoded or not, we try to reencode them in utf-8 if needed.
works perfectly with BNF server, that sends UNIMARC latin1 records. Should work with other servers too.

=head2 Z3950Search
Z3950Search($pars, $template);
Parameters for Z3950 search are all passed via the $pars hash. It may contain isbn, title, author, dewey, subject, lccall, controlnumber, stdid, srchany.
Also it should contain an arrayref id that points to a list of id's of the z3950 targets to be queried (see z3950servers table).
This code is used in acqui/z3950_search and cataloging/z3950_search.
The second parameter $template is a Template object. The routine uses this parameter to store the found values into the template.
