Bio::Tree::Tree - An Implementation of TreeI interface.

SYNOPSIS

    # like from a TreeIO
    my $treeio = new Bio::TreeIO(-format => 'newick', -file => 'treefile.dnd');
    my $tree = $treeio->next_tree;
    my @nodes = $tree->get_nodes;
    my $root = $tree->get_root_node;

DESCRIPTION

This object holds handles to Nodes which make up a tree.
