added a comment
- num_time_steps no longer passed into NetCDFOutput function
- it generates NetCDF4 output data file with unlimited time and data
  dimensions
 - added a write_output_post_run function for all outputters
   - (WIP) still need a test in renderer for this
- updated read_data so it takes 'time' as input and reads the data
  from netcdf file that is closest to user specified time. If time=None, it checks
  to see if data associated w/ one timestamp is in file and returns that. If
  file contains more than one timestamp, it raises exception. This is required for
  loading data if model was saved in mid-run
- updated and added tests
