[las_users] no wind vectors of COADS climatology

[emanuele lombardi <emanuele.lombardi@xxxxxxx>]

Las 7.0.2   Tomcat 6.0.14  

Dear LAS people,
I'm not able to plot wind vectors of COADS climatology. It seems that  
<composite></composite> lines in coads.xml don't work: LAS only shows those 
variables listed in <variables></variables>

I have the same problem with my own netcdf files, thus any help will be really 
apreciated.

Ciao from Italy,
Emanuele
