// .NAME vtkSQLiteDatabase - maintain a connection to an SQLite database
//
// .SECTION Description
//
// SQLite (http://www.sqlite.org) is a public-domain SQL database
// written in C++. It's small, fast, and can be easily embedded
// inside other applications. Its databases are stored in files.
//
// This class provides a VTK interface to SQLite. You do not need to
// download any external libraries: we include a copy of SQLite 3.3.16
// in VTK/Utilities/vtksqlite.
//
// If you want to open a database that stays in memory and never gets
// written to disk, pass in the filename ':memory:'.
//
// .SECTION Thanks
// Thanks to Andrew Wilson from Sandia National Laboratories for implementing
// this class.
//

// Description:
// Open a new connection to the database. You need to set the
