MultiCellDS saves `elapsed_time_in_phase` twice?

[drbergman]

As best I can tell, elapsed_time_in_phase is being saved twice:

1. PhysiCell/modules/PhysiCell_MultiCellDS.cpp

   Line 1769 in 3d7051f

   std::fwrite( &( pCell->phenotype.cycle.data.elapsed_time_in_phase ) , sizeof(double) , 1 , fp );

2. PhysiCell/modules/PhysiCell_MultiCellDS.cpp

   Line 1807 in 3d7051f

   std::fwrite( &( pCell->phenotype.cycle.data.elapsed_time_in_phase ) , sizeof(double) , 1 , fp );

Note: these two are appended to the list of labels in the output xml here:

1. PhysiCell/modules/PhysiCell_MultiCellDS.cpp

   Lines 942 to 950 in 3d7051f

   	name = "elapsed_time_in_phase";
   	units = "min";
   	size = 1;
   	data_names.push_back( name );
   	data_units.push_back(units);
   	data_sizes.push_back( size );
   	data_start_indices.push_back( index );
   	cell_data_size += size;
   	index += size;

2. PhysiCell/modules/PhysiCell_MultiCellDS.cpp

   Lines 1091 to 1099 in 3d7051f

   	name = "elapsed_time_in_phase";
   	units = "min";
   	size = 1;
   	data_names.push_back( name );
   	data_units.push_back(units);
   	data_sizes.push_back( size );
   	data_start_indices.push_back( index );
   	cell_data_size += size;
   	index += size;
