/**
* Storage is an easy way to store key/value pairs and other complicated
* data in a way that uses a variety of storage engines underneath.
*
* For most cases, we recommend the SqlStorage system as it will store
* data in a file in the app's sandbox. LocalStorage should ONLY be used
* for temporary data as it may be "cleaned up" by the operation system
* during low disk space situations.
