NAME
Graph::Easy::Layout::Grid - Grid management and size calculation

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:

        # +------+     +--------+

METHODS
This module injects the following methods into Graph::Easy:

  _prepare_layout()
        my ($rows,$cols,$max_x,$max_y, \@V) = $graph->_prepare_layout();

Returns two hashes ($rows and $cols), containing the columns and rows of the layout with their nec. sizes (in chars) plus the maximum framebuffer size nec. for this layout. Also returns reference of a list of all cells to be rendered.
