[Users] Carpet options to switch off mesh refinement

[dumsani]

I Ian,

I am not getting an informative error message. Instead the simulation 
aborts/terminates when interpolating coordinate values (I'm using the 
Llama multi-patch system), before initial data calculation. In an 
equivalent run where I have set a few levels, the simulation runs though 
properly. But I want to test without mesh refinement because my 
simulation crashes early; I just want to make sure the crash is not due 
to some funny stuffy occurring at grid boundaries, for instance.
