[Met_help] Mods for Point-Stat

[Ruifang Li]

John,
Thanks for your code. I used it to filter out some obs(UGRD >= 30.0 m/s) and
compare result with WRF-Var verification. The U RMSE is pretty close this
time and I also checked these ob/fcst paires in WRF-Var verification and
found out that they are treated as missing value. So it looks like that
quality control of obs makes big difference between MET and WRF-Var.

Thanks,
Ruifang
