Support one-dimensional VTK output #6
Description
Dan Parsons (d.parsons@hull.ac.uk) found that setting VTK output for HydroTrend caused his WMT run to fail. Here's the stack trace:

This is error is thrown for 1D output because offsets is empty; 2D output is fine.
Dan was able to work around this issue by using netCDF output instead of VTK.
This is likely low priority, since we should just use netCDF.
