I did not know somebody else worked on this. Sorry to hear that we 
duplicated the work.

I had a look at your code (haven't compiled it yet) but one thing I had

I can add some of your code, but some people still uses COARDS convention 
which is compatible with CF-etc. 

I notice that GMT checks for variable name "dimension" and "z". GMT driver 
should then reject netcdf CF or COARDS Convention except if these variables 
exists. This test seems to be good enough for the moment. 

At this point, I would like the netcdf driver to try to read the data even 
if it is not CF or COARDS.

Denis
