-\brief This interface provides a facility which enables a client to 
- order and access a set of arbitary data in a binary "tree"
- 
- Each "tree" is defined by a number of "clientnodes" which are
- ordered according to a client defined "key".
-
- A "clientkey" is a client specific entity which can be compared
- with a "clientnode" to determine which is the "greatest". In order
- to do this the client needs provide a comparison function for
- comparing a "clientnode" with a "clientkey", and a function to
- convert a "clientnode" into a "clientkey".
-
- The client is responsible for providing each "clientnode" in a
- tree. This will typically contain some client specific data, but
- will also need to contain a bintree "node" which is used to
- structurally relate each node to one another in the tree. A
- specific "node" may only belong to one tree at a time, but an
- individual "clientnode" may contain multiple of these if necessary.
-
-\par Implementation
-The implementation of this interface uses a top-down splaying algorithm.
-
-\par 
-"Splay trees", or "self-adjusting search trees" are a simple and
-efficient data structure for storing an ordered set.  The data
-structure consists of a binary tree, without parent pointers, and
-no additional fields.  It allows searching, insertion, deletion,
-deletemin, deletemax, splitting, joining, and many other
-operations, all with amortized logarithmic performance.  Since the
-trees adapt to the sequence of requests, their performance on real
-access patterns is typically even better.  Splay trees are
-described in a number of texts and papers [1,2,3,4,5].
-
-\par
-The code here is adapted from simple top-down splay, at the bottom
-of page 669 of [3].  It can be obtained via anonymous ftp from
-spade.pc.cs.cmu.edu in directory /usr/sleator/public.
-
-\par
-The chief modification here is that the splay operation works even
-if the item being splayed is not in the tree, and even if the tree
-root of the tree is NULL.  So the line:
-
-\par
-                           t = splay(i, t);
-
-\par
-causes it to search for item with key i in the tree rooted at t.
-If it's there, it is splayed to the root.  If it isn't there,
-then the node put at the root is the last one before NULL that
-would have been reached in a normal binary search for i.  (It's a
-neighbor of i in the tree.)  This allows many other operations to
-be easily implemented.

- * Description
- * ===========
- *              An implementation of top-down splaying
- *                  D. Sleator <sleator@cs.cmu.edu>
- *  	                     March 1992
- *
- * "Splay trees", or "self-adjusting search trees" are a simple and
- * efficient data structure for storing an ordered set.  The data
- * structure consists of a binary tree, without parent pointers, and
- * no additional fields.  It allows searching, insertion, deletion,
- * deletemin, deletemax, splitting, joining, and many other
- * operations, all with amortized logarithmic performance.  Since the
- * trees adapt to the sequence of requests, their performance on real
- * access patterns is typically even better.  Splay trees are
- * described in a number of texts and papers [1,2,3,4,5].
- *
- * The code here is adapted from simple top-down splay, at the bottom
- * of page 669 of [3].  It can be obtained via anonymous ftp from
- * spade.pc.cs.cmu.edu in directory /usr/sleator/public.
- * 
- * The chief modification here is that the splay operation works even
- * if the item being splayed is not in the tree, and even if the tree
- * root of the tree is NULL.  So the line:
- *
- *                            t = splay(i, t);
- *
- * causes it to search for item with key i in the tree rooted at t.
- * If it's there, it is splayed to the root.  If it isn't there,
- * then the node put at the root is the last one before NULL that
- * would have been reached in a normal binary search for i.  (It's a
- * neighbor of i in the tree.)  This allows many other operations to
- * be easily implemented, as shown below.
