Feature to input refseqs from NCBI database (for indexing, alignment, and circular features)

[RobJackson28]

The user should be able to input refseqs from the latest NCBI database v82 (ftp://ftp.ncbi.nlm.nih.gov/refseq/release/) to be able to index, use in alignment, and possibly even derive circular features such as genes/contigs.

Of most relevance, is likely this collection of files (which are viral refseq's, genomic, and in fasta nucleic acid (fna) format, which is the same as FASTA but specifically for nucleic acids like DNA or RNA, rather than protein amino acids): ftp://ftp.ncbi.nlm.nih.gov/refseq/release/viral/viral.1.1.genomic.fna.gz
