Bug: Error when domain = 1 grid cell

[tbohn]

I supplied MetSim with forcings, domain, state files, all in netcdf format, covering a domain that is 1 grid cell in extent (the 'lat' and 'lon' dimensions each have length 1).

I got the following error:
Traceback (most recent call last):

It appears that the problem was on my end: a typo in a dimension name when constructing the forcing file. It works now.
