=head2 name

  Usage    - print $subset_def->name() or $subset_def->name($name)
  Returns  - the subset def name (string)
  Args     - the subset def name (string)
  Function - gets/sets the subset def name

=cut

	$_[0]->{NAME} = $_[1] if ($_[1]);
	return $_[0]->{NAME};
}

=head2 description

  Usage    - print $subset_def->description() or $subset_def->description($desc)
  Returns  - the subset def description (string)
  Args     - the subset def description (string)
  Function - gets/sets the synonym description

=cut

sub description {
	$_[0]->{DESCRIPTION} = $_[1] if ($_[1]);
	return $_[0]->{DESCRIPTION};
}

=head2 as_string

  Usage    - $subset_def->as_string() or $subset_def->as_string("GO_SLIM", "GO Slim")
  Returns  - the subset def definition (string)
  Args     - the subset def definition (string)
  Function - gets/sets the definition of this synonym

=cut

=head2 equals

  Usage    - print $subset_def->equals($another_subset_def)
  Returns  - either 1 (true) or 0 (false)
  Args     - the subset def definition to compare with
  Function - tells whether this subset def definition is equal to the given argument (another subset def definition)

=cut
