NESTile now uses the Utils.isInt() function.

app/js/main.js

   var TileA = new NESTile();
   var TileB = new NESTile();
   TileB.setPixelIndex(0,0,2);
-  //var TileC = TileB.clone().flip(1);
-  var TileC = TileB.clone();
-  TileC.flip(1);
+  var TileC = TileB.clone().flip(1);
+  //var TileC = TileB.clone();
+  //TileC.flip(1);
 
   for (var i=0; i < 64; i++){
     console.log(TileC.pixels[i]);
   console.log("TileA does NOT match TileB: ", TileA.isEq(TileB) == -1);
   console.log("TileA does NOT match TileC: ", TileA.isEq(TileC) == -1);
   console.log("TileB DOES match TileC with Flag 1: ", TileB.isEq(TileC) == 1);
+
+  console.log(TileC);
+  console.log(TileC.dataArray);
+  console.log(TileC.pixels[7]);
 }
