averages all vars now except wind_speed and wind_direction
Haven't added gust yet

If -s is specified alone, script creates file from -s to end of the day
argparse now allows format YYYY-MM-DD

Got rid of the --no-empty flag
If empty ASCII file, doesn't create a nc file
If all ASCII files are empty, raise IO ERROR

setup.py now requires the pandas module
Fixed bug where some files were missing a data entry
Fixed bug where autoRun.bash pointed to wrong python file and python directory

Added globals software_version, data_level, data_stream, and input_filenames
Added netcdf daily regen
grabs a netcdf file for each day, and goes through all ascii files
netcdf files are created at /mnt/inst-data/regen_netcdf/aoss/tower/YYYY/MM

Will add unit tests later

Mixed up time and time_offset
time now seconds since epoch

Changed netcdf4 file format to netcdf4_CLASSIC
changed strlen from unlimited to 256
added a no-empty flag
made -o flag required

Without -s and -e, it converts each file into a new netcdf file
if -o is used, it converts it itno those output filenames
otherwise, it uses first stamp to name the files
Uh, doesn't do anything about empty .ascii files yet
Will have to ask about that

zlib for compression
chunksize for compression
both called in netcdf4's create variable instance

Only works when -s and -e are specified at the moment
Created draft nc file
might need to change altitude value
