// dojox.storage exposes the current available storage provider on this

//
// For more details on dojox.storage, see the primary documentation
// page at
// http://manual.dojotoolkit.org/storage.html
//
// Note for storage provider developers who are creating subclasses-
// This is the base class for all storage providers Specific kinds of
// Storage Providers should subclass this and implement these methods.
// You should avoid initialization in storage provider subclass's
// constructor; instead, perform initialization in your initialize()
// method.

// Arguments:

// Important note: if you are using Dojo Storage in conjunction with
// Dojo Offline, then you don't need to provide
