ENH: With topology change the header is written multiple times

See tutorial : incompressible/pimpleFoam/laminar/mixerVesselAMI2D/mixerVesselAMI2D-topologyChange

Output in postProcessing/AMI1/0/surfaceFieldValue.dat contains header information printed multiple times. Could this be avoided for topology change events?
