for anything that needs to be simultaneously aware of multiple references, eg
Queue's interval sharding code, liftover support, distributed GATK etc.
GenomeLocParser instances must now be used to create/parse GenomeLocs.
GenomeLocParser instances are available in walkers by calling either
-getToolkit().getGenomeLocParser()
or
-refContext.getGenomeLocParser()
This is an intermediate change; GenomeLocParser will eventually be merged
with the reference, but we're not clear exactly how to do that yet. This
will become clearer when contig aliasing is implemented.

The GAE half has all the walker specific code. The new "Abstract" GAE has the rest of the logic.
More refactoring to come, with the end goal of having a tool that other java analysis programs (Queue, etc.) can use to read in genomic data.

arg headers.

*** Three integration tests had to change: ***
RecalibarationWalkersIntegrationTest:
One of the tests was using the interval as the snp track, and wasn't supplying a DbSNP track (for CountCovariates)
SequenomValidationConverterIntegrationTest:
relies on Plink ROD which we've removed.
PileupWalkerIntegrationTest:
we no longer have implicit interval tracks, so there isn't a rod name over the specified region. Otherwise the same result.

This commit adds two important classes: Sample, which contains data about one sample; and SampleDataSource, which manages sample data a la ReferenceDataSource and ReadsDataSource.
This code should be stable, but it has not been integrated with existing walkers yet. That's the next commit.
In the meantime, feel free to experiment with the code - there are two basic example walkers in the playground.sample package. And PLEASE let me know if you see any errors/inconsistencies.
Note that this also adds a new dependency on SnakeYaml, a YAML parser.

command-line, which should allow us to get rid of some of the hackier calls in GenomeAnalysisEngine.

- Eliminate reduncancy of filter application.
- Track filter metrics per-shard to facitate per merging.
- Flatten counting iterator hierarchy for easier debugging.
- Rename Reads class to ReadProperties and track it outside of the Sting iterators.
Note: because shards are currently tied so closely to reads and not the merged triplet of <reads,ref,RODs>, the metrics
classes are managed by the SAMDataSource when they should be managed by something more general. For now, we're hacking
the reads data source to manage the metrics; in the future, something more general should manage the metrics classes.

you'd say:
@Requires(value={},referenceMetaData=@RMD(name="eval",type= VCFRecord.class))
Which is more in-line with what was done before. All instances in the existing codebase should be switched over.
