Backed out changes that attempted to address a pointer array using -1,0,1.

Jeremy pointed out that there might be problems with this.  Darn shame.

  * Log: ubi_SplayTree.h,v
- * Revision 3.0  1997/12/08 05:32:35  crh
- * This is a new major revision level because of a redesign of the handling
- * of the pointers in the ubi_trNode structure.  See ubi_BinTree for more
- * info.
+ * Revision 2.6  1997/12/23 04:02:20  crh
+ * In this version, all constants & macros defined in the header file have
+ * the ubi_tr prefix.  Also cleaned up anything that gcc complained about
+ * when run with '-pedantic -fsyntax-only -Wall'.
  *
- * Revision 2;  1995/02/27 - 1997/12/07:
- * Major changes: added the function ubi_sptSplay().
+ * Revision 2.5  1997/07/26 04:15:46  crh
+ * + Cleaned up a few minor syntax annoyances that gcc discovered for me.
+ * + Changed ubi_TRUE and ubi_FALSE to ubi_trTRUE and ubi_trFALSE.
  *
- * Revision 1; 93/10/15 - 95/02/27:
- * Added the ubi_tr defines.  See ubi_BinTree.h for more info.
+ * Revision 2.4  1997/06/03 05:22:56  crh
+ * Changed TRUE and FALSE to ubi_TRUE and ubi_FALSE to avoid causing
+ * problems.
+ *
+ * Revision 2.3  1995/10/03 22:19:37  CRH
+ * Ubisized!
+ * Also, added the function ubi_sptSplay().
+ *
+ * Revision 2.1  95/03/09  23:55:04  CRH
+ * Added the ModuleID static string and function.  These modules are now
+ * self-identifying.
+ * 
+ * Revision 2.0  95/02/27  22:34:55  CRH
+ * This module was updated to match the interface changes made to the
+ * ubi_BinTree module.  In particular, the interface to the Locate() function
+ * has changed.  See ubi_BinTree for more information on changes and new
+ * functions.
+ *
+ * The revision number was also upped to match ubi_BinTree.
+ *
+ *
+ * Revision 1.0  93/10/15  22:59:36  CRH
+ * With this revision, I have added a set of #define's that provide a single,
+ * standard API to all existing tree modules.  Until now, each of the three
+ * existing modules had a different function and typedef prefix, as follows:
+ *
+ *       Module        Prefix
+ *     ubi_BinTree     ubi_bt
+ *     ubi_AVLtree     ubi_avl
+ *     ubi_SplayTree   ubi_spt
+ *
+ * To further complicate matters, only those portions of the base module
+ * (ubi_BinTree) that were superceeded in the new module had the new names.
+ * For example, if you were using ubi_AVLtree, the AVL node structure was
+ * named "ubi_avlNode", but the root structure was still "ubi_btRoot".  Using
+ * SplayTree, the locate function was called "ubi_sptLocate", but the next
+ * and previous functions remained "ubi_btNext" and "ubi_btPrev".
+ *
+ * This was not too terrible if you were familiar with the modules and knew
+ * exactly which tree model you wanted to use.  If you wanted to be able to
+ * change modules (for speed comparisons, etc), things could get messy very
+ * quickly.
+ *
+ * So, I have added a set of defined names that get redefined in any of the
+ * descendant modules.  To use this standardized interface in your code,
+ * simply replace all occurances of "ubi_bt", "ubi_avl", and "ubi_spt" with
+ * "ubi_tr".  The "ubi_tr" names will resolve to the correct function or
+ * datatype names for the module that you are using.  Just remember to
+ * include the header for that module in your program file.  Because these
+ * names are handled by the preprocessor, there is no added run-time
+ * overhead.
+ *
+ * Note that the original names do still exist, and can be used if you wish
+ * to write code directly to a specific module.  This should probably only be
+ * done if you are planning to implement a new descendant type, such as
+ * red/black trees.  CRH
