Ember Data serializer example

gistfile1.js

// API return format is as so:
// {
// 	data: [
// 		{
// 			name: 'foo'
// 		}, 
// 		{
// 			name: 'bar'
// 		}
// 	]
// }
// Ember expects:
// {
// 	posts: [
// 		{
// 			name: 'foo'
// 		}, 
// 		{
// 			name: 'bar'
// 		}
// 	]
// }

	// Custom json root. The API returns objects in the "data" key.
	// We need to re-assign it to the singular version of the model name. 
	// So {data: {name: foo}} becomes {post: {name: foo}}
