[netCDF #QAK-764753]: Variables with different dimensions

Using time as an unlimited dimension seems the correct approach.
If you plan to use netcdf-3, then the time dimension needs to be
the first dimension. So something like this.

netcdf example {
dimensions:
    time = unlimited;
    x = ...;
    y = ...;

variables:
    float v1(time,x,y);
    float v2(time,x,y)
}

If you instead plan to use netcdf-4, then the unlimited time
dimension does not need to be the first; it can be in any position.
