pysam-0.8.2

• Pysam now wraps htslib 1.2.1 and samtools version 1.2
• Added CRAM file support to pysam
• New alignment info interface.
  • opt() and setTag are deprecated, use get_tag() and set_tag()
    instead.
  • added has_tag()
  • tags is deprecated, use get_tags() and set_tags() instead.
• FastqFile is now FastxFile to reflect that the latter permits
  iteration over both fastq- and fasta-formatted files.
• A Cython wrapper for htslib VCF/BCF reader/writer. The wrapper
  provides a nearly complete Pythonic interface to VCF/BCF metadata
  with reading and writing capability. However, the interface is still
  incomplete and preliminary and lacks capability to mutate the
  resulting data.
