Future plans
- For now the FASTA format is hard-coded in the program, but this may change should there be demand for it;
- This effectively limits NCBI Mass Sequence Downloader to sequence databases.
- As more NCBI sequence databases become available, they will be added to NCBI Mass Sequence Downloader.
- ~~Add argument parsing and value checking as referenced in #8 and #9.~~ Done!
