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 $product_count = $classification->product_count;

=head1 DESCRIPTION
Classification.pm represents a Classification object.
A Classification is a higher-level grouping of Products.
=head1 METHODS
=over
=item C<new($param)>
Description: The constructor is used to load an existing
classification by passing a classification
id or classification name using a hash.
Params: $param - If you pass an integer, the integer is the
classification_id from the database that we
want to read in. If you pass in a hash with
'name' key, then the value of the name key
is the name of a classification from the DB.
Returns: A Bugzilla::Classification object.
=item C<product_count()>
Description: Returns the total number of products that belong to
the classification.
Params: none.
Returns: Integer - The total of products inside the classification.
=item C<products>
Description: Returns all products of the classification.
Params: none.
Returns: A reference to an array of Bugzilla::Product objects.
=back
=head1 SUBROUTINES
=over
=item C<get_all_classifications()>
Description: Returns all classifications.
Params: none.
Returns: Bugzilla::Classification object list.
=item C<check_classification($classification_name)>
Description: Checks if the classification name passed in is a
