I just tried copying and pasting code from NcMLWriter, but ran across a 
difference in NetworkUtils API between the official Netcdf 2.2.22 jar 
file and 2.2.22 source bundle.

The latter contains NetworkUtils.canonicalizeWrite(String) but the 
former does not (presumably it is a different version of NetworkUtils).  
Is it just me or do others have this also?
