NAME
       Graph::Easy::Layout::Repair - Repair spliced layout with	group cells

SYNOPSIS
	       use Graph::Easy;

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

	       my $bonn	= Graph::Easy::Node->new(
		       name => 'Bonn',
	       );
	       my $berlin = Graph::Easy::Node->new(
		       name => 'Berlin',
	       );

	       $graph->add_edge	($bonn,	$berlin);

	       $graph->layout();

	       print $graph->as_ascii( );

	       # prints:

	       # +------+     +--------+
	       # | Bonn	| --> |	Berlin |
	       # +------+     +--------+

DESCRIPTION
       "Graph::Easy::Layout::Repair" contains code that	can splice in group
       cells into a layout, as well as repair the layout after that step.

       It is part of Graph::Easy and used automatically.

METHODS
       "Graph::Easy::Layout" injects the following methods into	the
       "Graph::Easy" namespace:

   _edges_into_groups()
       Put the edges into the appropriate group	and class.

   _assign_ranks()
	       $graph->_assign_ranks();

   _repair_nodes()
       Splicing	the rows/columns to add	filler cells will have torn holes into
       multi-edges nodes, so we	insert additional filler cells to repair this.

   _splice_edges()
       Splicing	the rows/columns to add	filler cells might have	torn holes
       into multi-celled edges,	so we splice these together again.

   _repair_edges()
       Splicing	the rows/columns to add	filler cells might have	put "holes"
       between an edge start/end and the node cell it points to. This routine
       fixes this problem by extending the edge	by one cell if necessary.

   _fill_group_cells()
       After doing a "layout()", we need to add	the group to each cell based
       on what group the nearest node is in.

       This routine will also find the label cell for each group, and repair
       edge/node damage	done by	the splicing.

EXPORT
       Exports nothing.
