C4::Circulation - Koha circulation module
=head1 SYNOPSIS

The functions in this module deal with circulation, issues, and
returns, as well as general information about the library.
Also deals with stocktaking.

=head2 transferbook
($dotransfer, $messages, $iteminformation) = &transferbook($newbranch, $barcode, $ignore_reserves);
Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
C<$newbranch> is the code for the branch to which the item should be transferred.
C<$barcode> is the barcode of the item to be transferred.
If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
Otherwise, if an item is reserved, the transfer fails.
Returns three values:
=head3 $dotransfer
is true if the transfer was successful.
=head3 $messages
is a reference-to-hash which may have any of the following keys:
=over 4
=item C<BadBarcode>
There is no item in the catalog with the given barcode. The value is C<$barcode>.
=item C<IsPermanent>
The item's home branch is permanent. This doesn't prevent the item from being transferred, though. The value is the code of the item's home branch.
=item C<DestinationEqualsHolding>
The item is already at the branch to which it is being transferred. The transfer is nonetheless considered to have failed. The value should be ignored.
=item C<WasReturned>
The item was on loan, and C<&transferbook> automatically returned it before transferring it. The value is the borrower number of the patron who had the item.
=item C<ResFound>
The item was reserved. The value is a reference-to-hash whose keys are fields from the reserves table of the Koha database, and C<biblioitemnumber>. It also has the key C<ResFound>, whose value is either C<Waiting> or C<Reserved>.
=item C<WasTransferred>
The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

Possible values are :

borrower declared it's card lost
=head3 DEBARRED
borrower debarred

=head3 WTHDRAWN
item withdrawn.
=head3 RESTRICTED
item is restricted (set by ??)
C<$issuingimpossible> a reference to a hash. It contains reasons why issuing is impossible.
Possible values are :

borrower has debts.
=head3 RENEW_ISSUE
renewing, not issuing

=head2 itemissues

Looks up information about who has borrowed the bookZ<>(s) with the
given biblioitemnumber.

include the fields from the C<items> table in the Koha database.
Additional keys include:
=over 4
=item C<date_due>
If the item is currently on loan, this gives the due date.
If the item is not on loan, then this is either "Available" or
"Cancelled", if the item has been withdrawn.
=item C<card>
If the item is currently on loan, this gives the card number of the
patron who currently has the item.
=item C<timestamp0>, C<timestamp1>, C<timestamp2>
These give the timestamp for the last three times the item was
borrowed.
=item C<card0>, C<card1>, C<card2>
The card number of the last three patrons who borrowed this item.
=item C<borrower0>, C<borrower1>, C<borrower2>
The borrower number of the last three patrons who borrowed this item.
