 * Page class describing an individual page and what things it

 * A DWORD is used to identify this page as the name of the storage
 * is the string form of this ID.  If we added a page every second,
 * it would take 136 years to overrun this counter, so we can
 * get away with saving it persistently.  I hope this software is
