=head1 NAME
Bio::Tree::NodeNHX - A Simple Tree Node with support for NHX tags
=head1 SYNOPSIS
use Bio::Tree::NodeNHX;
my $nodeA = Bio::Tree::NodeNHX->new();
my $nodeL = Bio::Tree::NodeNHX->new();
my $nodeR = Bio::Tree::NodeNHX->new();
my $node = Bio::Tree::NodeNHX->new();
$node->add_Descendents($nodeL);
$node->add_Descendents($nodeR);
print "node is not a leaf \n" if( $node->is_leaf);
=head1 DESCRIPTION
Makes a Tree Node with NHX tags, suitable for building a Tree. See
L<Bio::Tree::Node> for a full list of functionality.
=head1 FEEDBACK
=head2 Mailing Lists
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to
the Bioperl mailing list. Your participation is much appreciated.
