Save the files(tile json) to disk

[Outgoing]

You can add saving and loading files from disk.

private void LoadTile(Vector2 tileTms, Tile tile) {
            var url = string.Format(_mapzenUrl, _mapzenLayers, Zoom, tile.GetTileTms.x, tile.GetTileTms.y, _mapzenFormat, _key);
            var pathFile = PathSaveJsonFile + tile.GetTileTms.x + "-" + tile.GetTileTms.y;
            if (File.Exists(pathFile)) tile.ConstructTile(pathFile, true);
            else {     ObservableWWW.Get(url).Subscribe(
                        tile.ConstructTile, //success
                        exp => Debug.Log("Error fetching -> " + url)); }
        }
