[svn-r10094] Purpose:
New features & refactor Description: Add basic record removal (only handles level-0 B-trees currently) Add query routine to check the number of records in a B-tree Add debugging routine to check the address of the root node in the B-tree Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)
