Add hmmer-domtab indexing and its tests
Add hmmer-domtab writing and its tests
Update hmmer-domtab parser to deal with missing query accession
Adjust TogoWS tests to avoid DDBJ database (currently offline)
BGZF support (from another of my branches)
Adding sample SAM/BAM file originally from pysam project (MIT licenced)
Include version of ex1.sam with header
Include @HD line in ex1_header.sam
Refresh ex1.bam to show change in BGZF block sizes

This new file ex1_refresh.bam was created with samtools 0.1.18
and the header gets a BGZF block, and samtools has avoided
splitting reads accross block, whereas ex1.bam was from an
older samtools and all the blocks are size 65536 until the
end.
BGZF compressed GenBank file as test case
Include ex1_header.bam test file (with @HD and @SQ lines)
Include BGZF doctests in unit tests
Indexing BGZF (and GZIP) compressed files in Bio.SeqIO

Work from another of my branches.
Minimal tests for BGZF (see also doctests)
Include GZIP and BGZF compressed versions of example.fastq
Use example.fastq.bgz in test_bgzf.py
Testing BGZF random access
Simple BGZF block caching (must profile this)
Remove unused private attribute in BGZF code
Make Bio.bgzf.open(...) default to binary read mode
