* This class is a simple result set and meta data implementation.
* It can be used in Java functions that return a result set.
* Only the most basic methods are implemented, the others throw an exception.
* This implementation is standalone, and only relies on standard classes.
* It can be extended easily if required.
*
* An application can create a result set using the following code:
*
*
* SimpleResultSet rs = new SimpleResultSet();
* rs.addColumn("ID", Types.INTEGER, 10, 0);
* rs.addColumn("NAME", Types.VARCHAR, 255, 0);
* rs.addRow(0, "Hello" });
* rs.addRow(1, "World" });
