Analysis fails when blast database files do not already exist

[dfornika]

FluViewer has a feature to check whether or not a BLAST database has already been made based on the FluViewer fasta database file. If it hasn't then FluViewer will run makeblastdb to make it on-the-fly before proceeding.

We're using the run() function from the fluviewer.analysis module to do that here:

FluViewer/fluviewer/database.py

Line 115 in e315157

return_code = run(terminal_command, outdir, out_name, process_name, error_code)

...but we're not importing that module so we get:

NameError: name 'run' is not defined
