added some files to start supporting GBK files in flatfile-to-json.pl
changed stuff in flatfile-to-json.pm to accept --gbk flag
trivial edit to comments in Genbank.pm
added module required by GenBankParser.pm (Readonly.pm)
fixed GenBankParser - this parser was written in 2008, and it looks like many keywords changed.
added test for correct attributes in genbank file parsing
fixed test for parsing of attributes in gbk files to include some stuff I was manually deleting before - for now I'm just going to put everything into the JSON, need to confer with Rob/Gregg to decide how to construct the nclist - start at mRNA? start at gene level?
