[IDV #KDK-897162]: IDV 2.7 and HIRLAM hybrid files

Robb: what's the status of your work on these issues?

Ersnt:

1) there have been a few bug fixes in version 4.0.48.2.20090708.2010 that are 
not yet in idv, you can get from

 http://www.unidata.ucar.edu/software/netcdf-java/

in particular:

 ftp://ftp.unidata.ucar.edu/pub/netcdf-java/v4.0/ncIdv.jar

should replace the one in the idv classpath

2) heres the way the ncml should work, sorry i didnt notice the problems before:
