/*
* @brief This class provides functions to compute the lesion volume of a given lesion.
*        A lesion can be defined by a specific segmentation at each control-point - information type pair.
*        This segmentation and its parent image will be used inside the private 'GetSegmentationMaskVolume' function.
*        This function in turn uses the image statistics module (the 'ImageStatisticsContainerManager') to retrieve
*        the specific statistics values from a statistics node. However, if the statistics are not found,
*        a new 'QmitkImageStatisticsCalculationJob' is started. If the job is finished and the statistics are calculated,
*        a new statistics node is added to the data storage (or an existing statistics data node is updated).
