[netCDF #UBN-375372]: Sample programs

I assume you are trying to nf_inq_grps(int ncid, int *numgrps, int *ncids);
Netcdf has this funny trick that if an output is NULL, then it is ignored.
So, you actually need to call nf_inq_grps twice.
The first fime, you pass a variable for numgrps  and pass NULL for ncids.
Not sure offhand how to pass null in fortran. In any case, this returns 
the number of subgroups of the group specified by ncid.
Then you use numgrps to allocata an array of integers of size numgrps.
Then you call nf_inq_grps with both numgrps and the ncids array defined.
Upon return, the ncids array will contain the group ids of the subgroups.
