Partitioning syntax for Selection parameters
Input Record (example) : { 'ms0' : { 'msname':xxx1, 'spw':yyy } , 'ms1' : { 'msname':xxx2, 'spw':yyy } }
Output Record (example for partitioning on spw) : { '0' : { 'ms0' : { 'msname':xxx1, 'spw':yyy1 } , 'ms1' : { 'msname':xxx2, 'spw':yyy1 } } '1' : { 'ms0' : { 'msname':xxx1, 'spw':yyy2 } , 'ms1' : { 'msname':xxx2, 'spw':yyy2 } } }

CoordinateSystem and number of channels of original cube is passed in Output record is the ms's and data selection for each part.
also the Vector of outCsys and outnChan are the coordinatesystems and nchannel of the sub cube for each part. The image is divided in n part along spectral channel now if one of the sub cube has no match the the spw selection will have a "-1" for that part. The caller will have to deal with that for load balancing etc.\. Output Record (example for partitioning on spw) : { '0' : { 'ms0' : { 'msname':xxx1, 'spw': '0:5~10' } , 'ms1' : { 'msname':xxx2, 'spw':'0:20~25' }, 'nchan': 6, 'coordsys': { A record of the coordinatesystem of subcube 0}} '1' : { 'ms0' : { 'msname':xxx1, 'spw':'0:9~14' } , 'ms1' : { 'msname':xxx2, 'spw':'0:24~29' }, 'nchan':6, 'coordsys': { A record of the coordinatesystem of subcube 1} } } the coordsys keyed record can be use in CoordinateSystem:;restore to reconstrucr it is the same as the parameter outCsys

This currently only checks for the existence of at least one non-flagged row and returns the index of the first non-flagged row found. Otherwise returns SynthesisUtilMethods::NOVALIDROWS. This static method is called in the vis-iter loops to block invalid VBs from flowing down the pipes.
