When length(dvar)==1

[Mattriks]

I'm trying out GeoData.jl (master). I have a NetCDF file with 4 dims (lat,lon,time, and lev). lev only has 1 level (Vertical=20000.0).

using NCDatasets
ds = Dataset(filename)
dvar = ds["lev"] # length(dvar)==1
dvar[2]

NetCDF error: NetCDF: Index exceeds dimension bound (NetCDF error code: -40)

In GeoData, that error happens on this line.
I get the error with commit 9c2f79f, but not with commit 309aa76 (because of the correction in L240, which I know is necessary).

Ok that's just a typo, those lines should be inside the length check. Fixed on master.

I hadn't tested for dim of length 1.
