access nested data in dgrid

gistfile1.js

// http://dgrid.io/js/dgrid/test/Grid_rendering.html

// Apparently this is the only way to access nested data? And it's
// seriously legacy and only supported because of old DojoX stuff?

// data format goes thusly:
// {
// 	"_id": 1,
// 	"name": {
// 		"formatted": "first last",
// 		"last": "last",
// 		"first": "first"
// 	},
// 	"organization": {
// 		"name": "name"
// 	},
// 	"address": {
// 		"formatted": "street^/city, ST 23455",
// 		"street": "street",
// 		"city": "city",
// 		"state": "ST",
// 		"zip": "23455"
// 	}
// }
