isAggCol is not being considered in the column def

Hello there,

I was trying to use isAggCol property and I found a couple of issues with it:

In the function window.kg.Column the line self.isAggCol = config.isAggCol; is not taking into consideration the property isAggCol in the Column Defs. So I changed to the following code: self.isAggCol = colDef.isAggCol;
In the computed field nonAggColumns that is used for the menu, the filter should be the opposite. Instead of !col.isAggCol; it should be col.isAggCol

```
self.nonAggColumns = ko.computed(function () {
return self.columns().filter(function (col) {
return col.isAggCol;
});
});
```

Anyhow, that ended up working for me. Let me know if this is the proper way.

Regards,

Augusto

Locate the window.kg.Column function and the computed nonAggColumns field, then inspect how column definitions populate isAggCol and how the menu filters columns. Verify the intended behavior with the existing test suite, if present; done means column-definition values are honored and the menu includes the correct columns.
