JdbcTemplate variant with named parameter support.

NamedParameterJdbcTemplate is a wrapper around JdbcTemplate that adds support for named parameter parsing. It does not implement the JdbcOperations interface or extend JdbcTemplate, but implements the dedicated NamedParameterJdbcOperations interface.

If you need the full power of Spring JDBC for less common operations, use the `getJdbcOperations()` method of NamedParameterJdbcTemplate and work with the returned classic template, or use a JdbcTemplate instance directly.
