question: public static int [ ] analyzeGraphGrid ( TupleSet ts ) { int m , n ; Iterator iter = ts . tuples ( ) ; iter . next ( ) ; for ( n = 2 ; iter . hasNext ( ) ; n ++ ) { Node nd = ( Node ) iter . next ( ) ; if ( nd . getDegree ( ) == 2 ) break ; } m = ts . getTupleCount ( ) / n ; return new int [ ] { m , n } ; }
target:  Analyzes a set of nodes to try and determine grid dimensions. Currently looks for the edge count on a node to drop to 2 to determine the end of a row.
