185 Calculates the fine for a book.
187 The issuingrules table in the Koha database is a fine matrix, listing
188 the penalties for each type of patron for each type of item and each branch (e.g., the
189 standard fine for books might be $0.50, but $1.50 for DVDs, or staff
190 members might get a longer grace period between the first and second
191 reminders that a book is overdue).
194 C<$item> is an item object (hashref).
196 C<$categorycode> is the category code (string) of the patron who currently has
199 C<$branchcode> is the library (string) whose issuingrules govern this transaction.
201 C<$start_date> & C<$end_date> are DateTime objects
202 defining the date range over which to determine the fine.
204 Fines scripts should just supply the date range over which to calculate the fine.
206 C<&CalcFine> returns three values:
208 C<$amount> is the fine owed by the patron (see above).
210 C<$units_minus_grace> is the number of chargeable units minus the grace period
212 C<$chargeable_units> is the number of chargeable units (days between start and end dates, Calendar adjusted where needed,
213 minus any applicable grace period, or hours)
215 FIXME: previously attempted to return C<$message> as a text message, either "First Notice", "Second Notice",
216 or "Final Notice". But CalcFine never defined any value.
