/**
* {@link RowMapper} implementation that creates a {@code java.util.Map}
* for each row, representing all columns as key-value pairs: one
* entry for each column, with the column name as key.
*
* The Map implementation to use and the key to use for each column
* in the column Map can be customized by overriding {@link #createColumnMap}
* and {@link #getColumnKey}, respectively.
*
*
Note: By default, {@code ColumnMapRowMapper} will try to build a linked Map
* with case-insensitive keys, to preserve column order as well as allow any
* casing to be used for column names.
