Description

       "Graph::Easy::Layout::Grid" contains routines that calculate cell sizes on the grid, which is necessary

       Used automatically by Graph::Easy.

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.

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 |
