This file contains typedefs and constants used by the DatabaseKeyB
base class, Btree class, and Btree node class.

Changes:
==============================================================
02/22/2002: Changed the BtreeNodeOrder_t, BtreeSize_t, 
BtreeKeyCount_t, BtreeKeyLocation_t to native integer types.

02/22/2002: Added the BtreeNodeOrder, BtreeSize, BtreeKeyCount, 
and the BtreeKeyLocation platform independent types.
