help in reading different dimensions of variables

Hello, thanks for the great module.
I must read some variables of the Geo2D type.
Each variable has 3 dimensions: Time, south_north, west_east.
e.g:
```
float MYVAR(Time=73, south_north=80, west_east=100);
:units = "ppb vol";
:long_name = "MYVAR";
```

how can I read each variable point? If I use reader.getDataVariable("MYVAR") I get a single array of 73 elements, which I suppose is a slice of the data.

Can you please post an example about how I can get the remaining data points?
thank you.
