Tiny typo in groups_hierarchy_create_group()

Hi David-

I’m programmatically adding BP groups using the wrapper function groups_hierarchy_create_group() and found a one-letter typo.

function groups_hierarchy_create_group( $args = '' ) {
	if( $group_id = groups_create_group( $args ) ) {
		if( isset( $args['parent_id'] ) ) {
			$group = new BP_Group_Hierarchy( $group_id );
			$group->parent_id = (int)$args['parent_id'];
			$group->save();
		}
		return $group_id;
	}
	return false;
}

$group = new BP_Group_Hierarchy( $group_id ); should read
$group = new BP_Groups_Hierarchy( $group_id );.

Thanks for the excellent plugin!
