- support construct face from subset of labels. - additional cellModel face() method to return a single face. - reduce some allocations in cellModel centre/mag methods STYLE: mark old cellModeller methods as compile-time deprecated - deprecated in 2017, but not marked as such STYLE: indentation, spacing in some headers
