Simplified interface for SQLite.
Updated for Sqlite 3 by Tim Anderson (tim@itwriting.com)
Note: NOT COMPLETE for version 3, just minimal functionality
Adapted from file created by Pablo Pissanetzky (pablo@myhtpc.net)
which was based on SQLite.pas by Ben Hochstrasser (bhoc@surfeu.ch)

// N is an integer. These value of these wildcard literals can be set
// using the routines listed below.
//
// In every case, the first parameter is a pointer to the sqlite3_stmt
// structure returned from sqlite3_prepare(). The second parameter is the
// index of the wildcard. The first "?" has an index of 1. ":N:" wildcards
// use the index N.
//
// The fifth parameter to sqlite3_bind_blob(), sqlite3_bind_text(), and
//sqlite3_bind_text16() is a destructor used to dispose of the BLOB or
//text after SQLite has finished with it. If the fifth argument is the
// special value SQLITE_STATIC, then the library assumes that the information
// is in static, unmanaged space and does not need to be freed. If the
// fifth argument has the value SQLITE_TRANSIENT, then SQLite makes its
// own private copy of the data.
//
// The sqlite3_bind_* routine must be called before sqlite3_step() after
// an sqlite3_prepare() or sqlite3_reset(). Unbound wildcards are interpreted
// as NULL.
