[visad] VisAD with Java 1.7 on Windows 7

Hello all,

I am re-visiting some visad concepts/ideas, and have managed to get the 
source/examples compiling with Java 1.7 on a Windows 7 notebook. So far, so 
good, though I was caught out by the Java3D dynamic link libraries (took a few 
hours to solve this).

Regards,
JimK.
