Some parts of `ImageStatisticsCalculator` have changed, especially the usage of `ImageStatisticsContainer`.
=Before=
```
//instantiate ImageStatisticsCalculator and add image
mitk::ImageStatisticsCalculator::Pointer calculator = mitk::ImageStatisticsCalculator::New();
calculator->SetInputImage(image);
//statistics are calculated for each time step on the fly if requested
unsigned int startT = 0;
unsigned int endT = image->GetTimeSteps()
for (unsigned int t = startT; t<)endT; t++){
//request statistics for current timestep
StatisticsContainer::Pointer statistics = calculator->GetStatistics(t);
double mean = statistics->GetMean();
double median = statistics->GetMedian();
double min = statistics->GetMin();
double max = statistics->GetMax();
const vnl_vector<int> minIndex = statistics->GetMinIndex();
const HistogramType::Pointer = statistics->GetHistogram();
}
```
