NAME
       Graph::Easy::Node::Cell - An empty filler cell

SYNOPSIS
	       use Graph::Easy;
	       use Graph::Easy::Edge;

	       my $graph = Graph::Easy->new();

	       my $node = $graph->add_node(’A’);

	       my $path = Graph::Easy::Node::Cell->new(
		 graph => $graph, node => $node,
	       );

	       ...

DESCRIPTION
       A "Graph::Easy::Node::Cell" is used to reserve a cell in the grid for
       nodes that occupy more than one cell.

       You should not need to use this class directly.

METHODS
       error()

	       $last_error = $cell->error();

	       $cvt->error($error);		       # set new messags
	       $cvt->error(’’);			       # clear error

       Returns the last error message, or ’’ for no error.

       node()

	       my $node = $cell->node();

       Returns the node this filler cell belongs to.
