THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Instance Data
The view framework exposes a way to store key/value pair "instance data". This data is scoped to a given view instance and user. Instance data is meant to be used for information such as "user prefs" or other lightweight information that supports the experience of your view application. You can access the instance data get and put methods from the ViewContext object, which is available from your view server-side resources.
