=head1 NAME
Bugzilla::Classification - Bugzilla classification class.
=head1 SYNOPSIS
use Bugzilla::Classification;
my $classification = new Bugzilla::Classification(1);
my $classification = new Bugzilla::Classification({name => 'Acme'});
my $id = $classification->id;
my $name = $classification->name;
my $description = $classification->description;
my $sortkey = $classification->sortkey;
my $product_count = $classification->product_count;
my $products = $classification->products;
=head1 DESCRIPTION
Classification.pm represents a classification object. It is an
implementation of L<Bugzilla::Object>, and thus provides all methods
that L<Bugzilla::Object> provides.
The methods that are specific to C<Bugzilla::Classification> are listed
below.
A Classification is a higher-level grouping of Products.
=head1 METHODS
=over
=item C<product_count()>
Description: Returns the total number of products that belong to
the classification.
Params: none.
Returns: Integer - The total of products inside the classification.
=item C<products>
Description: Returns all products of the classification.
Params: none.
Returns: A reference to an array of Bugzilla::Product objects.
