Added the "version" parameter which was missing from the function call for calwf3.py and added an example for usage as no input filename is needed or should be provided if the version is requested. If a filename is provided, it is ignored in this case. Removed the "output" parameter as the underlying C code does not actually support specification of an output filename. Updated comments as appropriate.
