A checkpoint commit of two BAM reading projects going on simultaneously. These two projects 

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).
