Making predicate script mode 744
Making a semi valid predicate that filters only depressing weather measurements.

Depressing weather means ((windspeed > 40 && tempF < 30) || (windspeed = 0 && tempF > 95)).
After fixing the earlier issues, it appears I can now use the predicate code in a MR job to filter data.
The resulting output looks legit as well.
I may extract the predicate code into its own project due to how large it is getting.
