A Cursor implementation that exposes results from a query on a
SQLiteDatabase.

Remarks
A Cursor implementation that exposes results from a query on a SQLiteDatabase.
SQLiteCursor is not internally synchronized so code using a SQLiteCursor from multiple threads should perform its own synchronization when using the SQLiteCursor.
