This was just a quick overview of what I'm planning, as well as the grid initialization.  There was one section in lines 49-51 where I try to create a two-dimensional array of empty Cell objects.  Was this the correct syntax?

The code to handle a click on a cell should be coming up next - let me see if I can pull it up tonight.
```javascript
if (numRow === NaN || numRow < 5 || numCol === NaN || numCol < 5 || numMines === NaN || numMines < 1) {
```
