Certain variable groups don't need to be stored in checkpoint files because they are recomputed on recovery. Kranc should work out which these are, and by default set the checkpoint=no tag for those groups. Lacking this intelligence, Kranc should provide an interface for the user to manually specify that certain groups should not be checkpointed. This would avoid having to programatically implement this in ML_BSSN_Helper in the McLachlan code.
