Detailed Description
       The StackPager provides a repository to stash and retrieve working data in last-in-first-out order.

       The use of a mempager to support it's operation allows storage of arbitrary sized objects with no fixed limit.

	   Create a buffer of known capacity for objects of a specified size.
       FixedBuffer (const FixedBuffer &fb)
	   Create a copy of an existing fixed size buffer and duplicate it's contents.
       virtual ~FixedBuffer ()
	   Destroy the fixed buffer and free the memory used to store objects.
       FixedBuffer & operator= (const FixedBuffer &fb)
       bool isValid (void)

   Protected Member Functions
       size_t onPeek (void *buf)
	   Return the first object in the buffer.
