=head1 DESCRIPTION

CGI::Widget::HList provides look-and-feel for displaying a 
CGI::Widget::HList::Node tree graph.  For more information, 
see L<CGI::Widget::HList::Node>.

This module is where image configurations, node rendering, 
and connector rendering methods are stored in the form of 
callbacks.

Check ex/ for example scripts

=head2 Constuctors

CGI::Widget::HList has only one constructor: new().

For convenient access to the CGI::Widget::HList::Node
constructor, you can call the node() method.

new() accepts the following parameters, with optional leading dash.
All parameters are optional.

 Parameter                   Purpose
 -------------------------------------------------------------------
 root                        Root node of the tree to be rendered

 Images to be used in the HTML rendering of the tree:
 img_open,img_close,img_leaf,img_trunk,img_branch,img_corner,img_spacer                  

 The rendering methods themselves.  All are callbacks:
 render_node,render_branch,render_spacer,render_trunk                             

The rendering methods default to sensible code that uses the (also
default) images.  This can all be over-ridden.  See Methods.

=head2 Methods

Interpreted in a scalar context, the object is overloaded to return 
the html for the HList.  Easy!
