1. Use production servers.
2. Fix vcf header truncation by using Jon Anthony's code to read header in a more sensible fashion, just reading one line at a time until a records without leading # is encountered.
3. Refactored code that gets stats for local vcf file so that it is easy to capture streamed vcf (catInputServer) immediately after vcfstatsalive server is run.  That way, same regions of vcf file are streamed to catInputServer (for creating a file to debug a problem) as those streamed to vcfstatsAlive server.
4. Don't show the tooltip for the reference donut chart as it still is unreliable in terms of location and also shows when it shouldn't (when 'all' references are selected...)
Don't show tooltip for reference donut chart right now as it still is a bit buggy.
