If we want to keep the parameter steering interface for CarpetRegrid 
then the logging problem still persists. In order to solve it I suggest 
to introduce a new parameter in Formaline

STRING steered_parameters_log_exclusion_list "Parameters for which 
runtime changes should not be logged" STEERABLE=always
{
   "" :: "whitespace-separated list of parameter names"
} "CarpetRegrid::coordinates"

Are there additional parameters which should be excluded from the loglist ?
