1. Allow nccopy to apply filters, especially on the output file. This provides a third way to do this other than using ncgen or programatically 2. Make sure that even if the filter code is not available, it is possible to see the filter id and parameters for variables using e.g ncdump -hs. 3. Fix bug in nccopy so that the input file does not necessarily have to be netcdf-4. 4. At last minute decided to change to using a single "_Filter" attribute for ncgen 5. Added a test to tst_filter.sh to generate C code using ncgen.
