=head1 NAME
X12::Parser::Tree - Object structure representing the X12 cf file.
=head1 SYNOPSIS
use X12::Parser::Tree;
#create a new Tree object
my $node = X12::Parser::Tree->new();
#set the name of the node/loop
$node->set_name('1000A');
#set the name of the parameters used to determine start of a loop
$node->set_loop_start_parm('NM1', '41', 1);
#create a new Tree object and set it as the child
my $child_node = X12::Parser::Tree->new();
$node->add_child($child_node);
=head1 DESCRIPTION
This module represents the cf file as a object structure. This class is
used by the L<X12::Parser> and L<X12::Parser::Cf>. Unless you plan to modify the
parser or such you would not need to access this class directly.
