All issues with reverse_iterators not working
properly and one harmless bad-memory access were
fixed.


Changes: All issues with root node pointer == NULL have been fixed. A crash when attempting to copy-construct an empty btree or when trying to remove a nonexistent item from an empty btree has been fixed. A crash when running verify() on an empty btree object has been fixed. Now the root node is freed when the last item is removed.


Changes: All issues with reverse_iterators not working properly and one harmless bad-memory access were fixed.


Changes: This release fixed a possibly illegal memory access during a find() or derived lookup call, if the queried key is larger than any item contained in the tree.


Changes: This release introduces the demonstration program wxBTreeDemo. This program draws illustrations of the B+ trees constructed by the STX B+ Tree template classes. It allows the user to select different types of B+ tree instantiations: integer or string keys and different slot numbers. The user may insert and erase key/data pairs from the tree and run different search operations. The demo program uses the cross-platform wxWidgets toolkit and can be compiled on Linux, Windows, and Mac OS X.
