Opening nc.zip files

Hi Pauline,

I think you have an old version of the grib-*.jar library on your 
classpath before the netcdf-*.jar file. The 
ucar.unidata.io.RandomAccessFile class is distributed in both library 
files and if those two libraries aren't in sync it can cause trouble.

The versions in netcdfAll-2.2.20.zip should match up. Here's the version 
info from the grib jar file:

Built-On: 2007-05-15 13:13:58
Implementation-Version: 5.1.03
