/**
 * A SimpleJdbcInsert is a multi-threaded, reusable object providing easy insert
 * capabilities for a table. It provides meta data processing to simplify the code
 * needed to construct a basic insert statement. All you need to provide is the
 * name of the table and a Map containing the column names and the column values.
 *
 * <p>The meta data processing is based on the DatabaseMetaData provided by the
 * JDBC driver. As long as the JDBC driver can provide the names of the columns
 * for a specified table than we can rely on this auto-detection feature. If that
 * is not the case, then the column names must be specified explicitly.
 *
 * <p>The actual insert is being handled using Spring's
 * {@link org.springframework.jdbc.core.JdbcTemplate}.
 *
 * <p>Many of the configuration methods return the current instance of the SimpleJdbcInsert
 * to provide the ability to chain multiple ones together in a "fluent" interface style.
