** This file contains code used to implement the DECLARE...CURSOR syntax

**
** Do not confuse SQL cursors and B-tree cursors.  An SQL cursor (as
** implemented by this file) is a user-visible cursor that is created
** using the DECLARE...CURSOR command and deleted using CLOSE.  A
** B-tree cursor is an abstraction of the b-tree layer.  See the btree.c
** module for additional information.  There is also a VDBE-cursor that
** is used by the VDBE module.  Even though all these objects are called
** cursors, they are really very different things.  It is worth your while
** to fully understand the difference.
