Colin Campbell 32c5ef613d Use hour or day deltas to calculate overdue durations 
If durations are calculated by subtraction they will use units
larger than those we care about and these are not convertable
to the smaller units we are attempting to enumerate
Use the appropriate delta methods to calculate theee fines

Adds a separate hours_between method to calendar
This should strictly be checking opening hours (of which
closed days are a special case) of the relevant branch
These need adding to branches

C4::Circulation::Fines - Koha module dealing with fines
=head1 SYNOPSIS
use C4::Overdues;
=head1 DESCRIPTION
This module contains several functions for dealing with fines for
overdue items. It is primarily used by the 'misc/fines2.pl' script.
=head1 FUNCTIONS
=head2 Getoverdues
$overdues = Getoverdues( { minimumdays => 1, maximumdays => 30 } );
Returns the list of all overdue books, with their itemtype.
C<$overdues> is a reference-to-array. Each element is a
reference-to-hash whose keys are the fields of the issues table in the
Koha database.

=head2 CalcFine
($amount, $chargename, $daycounttotal) = &CalcFine($item,
$categorycode, $branch,
$start_dt, $end_dt );
Calculates the fine for a book.
The issuingrules table in the Koha database is a fine matrix, listing
the penalties for each type of patron for each type of item and each branch (e.g., the
standard fine for books might be $0.50, but $1.50 for DVDs, or staff
members might get a longer grace period between the first and second
reminders that a book is overdue).
C<$item> is an item object (hashref).
C<$categorycode> is the category code (string) of the patron who currently has
the book.
C<$branchcode> is the library (string) whose issuingrules govern this transaction.
C<$start_date> & C<$end_date> are DateTime objects
defining the date range over which to determine the fine.
Fines scripts should just supply the date range over which to calculate the fine.
C<&CalcFine> returns four values:
C<$amount> is the fine owed by the patron (see above).
C<$chargename> is the chargename field from the applicable record in
the categoryitem table, whatever that is.
C<$daycount> is the number of days between start and end dates, Calendar adjusted (where needed),
minus any applicable grace period.
FIXME - What is chargename supposed to be ?
FIXME: previously attempted to return C<$message> as a text message, either "First Notice", "Second Notice",
or "Final Notice". But CalcFine never defined any value.

Updates the fine owed on an overdue book.

C<$borrowernumber> is the borrower number of the patron who currently
has the book on loan.

C<$description> is a string that must be present in the description of
the fine. I think this is expected to be a date in DD/MM/YYYY format.
C<&UpdateFine> looks up the amount currently owed on the given item
and sets it to C<$amount>, creating, if necessary, a new entry in the
accountlines table of the Koha database.
