Added the basic meta-information to the output files including fileformat, fileDate, INFO(NS/DP) and FILTER(q10). Source, reference, etc. still need to be filled out.
Output file now shows QUAL values for SNV's and deletions. Still need to determine how insertion QUAL values are calculated.
Added an argument for a FASTA file (currently not used/required). Also added an import for Bio.SeqIO which may be used later.
