Class VolumeDataContext

The VolumeDataContext directly cooresponds to the native-level VDC, and contains the minimal information needed to construct and render a volume.

The SeriesDataContext field will be populated with the DICOM information if this object was created through loadDICOMDir with readStandardDICOMTag=true or it was created using loadVolumeFromSeries
