Alternative Data Access Methods

Here is an example script to read the SPDF filelist.gz catalog, and new download CDFs and netCDFs since the last time the script was run. This example selects only CDF and netCDF files, but that constraint can be removed. The script outputs spdf_new_files and spdf_deleted_files from the difference of new and old SPDF file lists, and retrieves new files, skipping any patterns in spdf_skipfiles or selecting only files matching patterns in spdf_choosefiles.
