To make the demo work, you need to create an Account in Kinvey at https://console.kinvey.com/. After the account is created, you can get the following values from the API Console

.value( 'KINVEY_AUTH' , 'Basic a2lkXy1KZWlDTFpNNTphMGFkOTliY2RhMDE0YzFkYWQyNDAwMGQ5ZDBmNjY2OA==')
.value( 'KINVEY_APP_URL' , 'https://baas.kinvey.com/appdata/kid_-JeiCLZM5/')

The credentials will be specific to your account. This demo shows using the http REST verbs to manipulate the user object.
