Detailed Description

StoredNode is the base class for all structures used as headers for pages of stored objects.

NOTE: Great caution should be used when definining and modifying stored data structures. When defining new ones, plan ahead for future changes (e.g. by defining reserved fields and filling them with reserved patterns.) Before modifying existing ones, consider whether your change might invalidate extant stored databases; it may be possible to make the change in a backwards-compatible fashion.
