**What it does**

Accepts associated fastq files, SAMtools idxstats files and **vSNP: add zero coverage** metrics files and extracts information from them
to produce an Excel spreadsheet containing statistics for each sample.  The samples can be single or paired reads, and all associated inputs
can be either single files or collections of files.  The output statistics include reference, file size, mean read length, mean read quality,
reads passing Q30, total reads, all mapped reads, unmapped reads, unmapped reads percentage of total, reference with coverage, average depth
of coverage and good SNP count.
