default boolean columnNameStartsWith(String columnName, String prefix) {
        return columnName.startsWith(prefix);
    }
Return whether the column name starts with the given prefix, according to the matching strategy of this
{@code ColumnNameMatcher}. This method is used by reflective mappers to short-circuit nested mapping when no
column names begin with the nested prefix.

By default, this method returns {@code columnName.startWith(prefix)}. Third party implementations should override
this method to match prefixes by the same criteria as {@link #columnNameMatches(String, String)}.

@param columnName the column name to test
@param prefix the prefix to test for
@return whether the column name begins with the prefix.
