RowProcessor implementation for converting batches of rows extracted from any implementation of AbstractParser into columns of objects.
This uses the value conversions provided by Conversion instances.
For each row processed, a sequence of conversions will be executed to generate the appropriate object. Each resulting object will then be stored in a list that contains the values of the corresponding column.
During the execution of the process, the batchProcessed(int) method will be invoked after a given number of rows has been processed.
The user can access the lists with values parsed for all columns using the methods getColumnValuesAsList(),
getColumnValuesAsMapOfIndexes() and getColumnValuesAsMapOfNames().
After batchProcessed(int) is invoked, all values will be discarded and the next batch of column values will be accumulated.
This process will repeat until there's no more rows in the input.
