Offer the PassThroughFieldSetMapper as part of the final 1.0 release

[tonyjoe]

I'm currently evaluating Spring Batch 1.0.m3. In that release you have a sample class org.springframework.batch.sample.mapping.PassThroughFieldSetMapper. I believe this class is very useful and should be moved out of the samples and somewhere under the org.springframework.batch.io.file* package.

While it's nice to think that everyone using the framework will conform to laying out their processes as is recommended (i.e. actually implementing a "real" mapper), in reality people may cut corners for the sake of time. I know for some of my tasklets this really came in handy.

Sounds reasonable. Why not open a JIRA?

Done --> http://jira.springframework.org/browse/BATCH-269
