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;

Classification.pm represents a Classification object.
A Classification is a higher-level grouping of Products.
=head1 METHODS
=over
=item C<new($param)>

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.
