> some field storage strategies can be much improved by immediate break vs. the break-and-load
currently provided.
> this adds another break option, which makes it more advantageous to have member variables
of the enum that indicate it's a break/load etc. vs. doing a bunch of grouped == checks.
> The BREAK option should cause an early termination with include == false in the ParallelReader
when the BREAK before any other field, then the document should not be loaded from that reader.
This is fairly easy to validate with a test, which is included in the patch.
