[wxqc] Weird Summary contained in daily report

This was my fault. I have been working on importing more data into my 
system over the last few days, and the bad summary was generated as a 
result of this.

In particular, I now import worldwide METAR data and worldwide CWOP 
data, though for data outside the US, there is no analysis performed.

The root cause of the problem was that when I imported the CWOP data, 
for those stations that reported more than once per 15 minutes, I saw 
different data records than the ones that MADIS say. This meant that 
when the emails were generated, the summary covered both MADIS records 
(which had good error fields) and direct CWOP records (which had 99999 
as a marker for unknown error). This also explains why the number of 
samples for the day has gone up from 96 (4 times per hour) to 172 (in my 
case). Hopefully, tomorrow, things will be back to normal.

Does anybody fancy trying to do worldwide QC?
