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.
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.
The actual insert is being handled using Spring's JdbcTemplate. 
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.
