- Change the name of the package to nbci-blast+ to be avoid conflicts
with ncbi-blast packaged in "ncbi" and to be aligned with other systems
(e.g. Debian world)
- Update to version 2.7.1
	* BLAST+ 2.7.1: October 23, 2017
	- Improvements::
	    Provided an upper limit on the number of threads for BLAST+ 
	search applications.

	applications.

	* BLAST+ 2.6.0: January 09, 2017
	- New features::
	    Handle bare accessions on blastdb_aliastool.
	    Change defaults for output formats 6, 7, and 10 to incorporate 
	version in accessions.
	- Improvements::
	    Add support for NCBI_DONT_USE_LOCAL_CONFIG and 
	NCBI_DONT_USE_NCBIRC environment variables.
	    Better runtime performance in blastdbcmd when the entry_batch 
	parameter is used.
	    SAM output improvements.
	    Changed gapped alignment starting point to minimize the chance to 
	produce sub-optimal alignments.
	    For custom matrices absent from the util/tables source file, use 
	BLOSUM62 for reporting number of positives.
	    Added long_seqids flag to blastdbcmd to use long (legacy) NCBI 
	Seq-id format.
	- Bug fixes::
	    Fixed issue with missing alignments in blastx.
	    Fixed problem processing accession.version in makeblastdb.
	    Fixed blastdbcmd problem with local IDs.

	    Added output format for taxonomic organism report.
	    Support for bare accessions in FASTA and BLAST reports.
	- Improvements::
	    -remote option connects to NCBI via HTTPS. This adds a dependency 
	on GNUTLS (see https://www.ncbi.nlm.nih.gov/books/NBK279690/)
	    Pre-fetch sequences for formatting.
	- Bug fixes::
	    Fixed improper functioning of output format 6 tokens ssciname, 
	staxid, sscinames and staxids.

	- New features:
	    Introduced multi-threaded traceback for blastp, blastx, tblastn 
	and tblastx.
	    Added new tabular format specifiers for taxonomic information 
	(staxid, ssciname, scomname, sblastname, skingdom) that correspond to 
	the first subject ID.
	- Improvements:
	    Speed up makeblastdb runtime performance with input consisting of 
	many ambiguities.
	    Better support for 'bare' IDs in taxid_map option to makeblastdb.
	    Score U (selenocysteine) as C (not X) in protein-protein and 
	translated searches.
	- Bug fixes:
	    Corrected E-value computation in finite-size correction.
	    Removed memory leak from rpsblast.
	    Made handling of ambiguities in subjects identical when using 
	FASTA and BLAST database inputs.
	    makeblastdb no longer replaces tabs in definition line by '#'.

	    Corrected handling of subject_loc.
	
	* BLAST+ 2.3.0: December 21, 2015
	- New features:
	    Added new PSIBLAST command line options to support saving PSSM 
	and checkpoint files for each iteration and calculate checkpoint and 
	PSSM for the last iteration.
	    Added unique subject sequence query coverage to tabular output.
	    Added support single file JSON and XML2 Blast output format.
	    Beta release of SAM output format.
	    Treat N subject sequences, entered with the -subject argument 
	(bl2seq mode), as one search set rather than N sets.
	- Improvements:
	    makeblastdb ignores and warns users about empty sequences in 
	input.
	    BLAST+ only accepts "obinary" windowmasker files for performance 
	reasons.
	- Bug fixes:
	    Best hits processing multi-threaded context.
	    Fixed memory leak when invoking composition based statistics with
