are works in progress, and this checkin will provide a baseline against which to gauge
improvements to both projects.
Low-memory BAM protoshards (disabled by default):
- Currently passing ValidatingPileupIntegrationTest.
- Gets progressively slower throughout the traversal, but should run at least as fast as original implementation.
- Uses 10+ file handles per BAM, but should use 3.
BAM performance microbenchmark test system:
- Currently tests performance of BAM reading using SAM-JDK vs. GATK
- Tests do not hit all GATK performance hotspots.
- New tests that require input data in a slightly different form are hard to implement.
- Output of test results is not easily parseable (investigating Google Caliper for possible improvements).

svn's logs:
- Copied BAM indexing engine from Picard back into the GATK anticipating
shard merging algorithm. Tried to leave most of the building blocks in
Picard. If this turns into a logistical nightmare, I'll merge the building
blocks into the GATK as well.
- Reorganized the org.broadinstitute.sting.gatk.datasources package, giving
better separation of query and management functionality for reads, ref, rmd,
and samples.
- Merged Shard building blocks into org.broadinstitute.sting.gatk.datasources.
reads package, indicating it's current strong relationship with the reads,
rather than the general unifying element I wish this would be.
- Collapsed BAMFormatAwareShard into Shard.
