/**
 * A SimpleJdbcInsert is a multithreaded, 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 then 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 handled using Spring's {@link 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.
