 //##Documentation
 //## @brief Describes the geometry of a data object
 //##
 //## At least, it can return the bounding box of the data object. 
 //##
 //## The class holds 
 //## \li a bounding box which is axes-parallel in intrinsic coordinates 
 //## (often integer indices of pixels), to be accessed by 
 //## GetBoundingBox()
 //## \li a transform to convert intrinsic coordinates into a 
 //## world-coordinate system with coordinates in millimeters 
 //## and milliseconds (all are floating point values), to 
 //## be accessed by GetIndexToWorldTransform()
 //## \li a life span, i.e. a bounding box in time in ms (with 
 //## start and end time), to be accessed by GetTimeBounds(). 
 //## The default is minus infinity to plus infinity.
 //##
 //## Geometry3D and its sub-classes allow converting between 
 //## intrinsic coordinates (called index or unit coordinates) 
 //## and world-coordinates (called world or mm coordinates), 
 //## e.g. WorldToIndex.
 //## In case you need integer index coordinates, provide an
 //## mitk::Index3D (or itk::Index) as target variable to 
 //## WorldToIndex, otherwise you will get a continuous index
 //## (floating point values).
 //##
 //## An important sub-class is SlicedGeometry3D, which descibes 
 //## data objects consisting of slices, e.g., objects of type Image.
 //## Conversions between world coordinates (in mm) and unit coordinates 
 //## (e.g., pixels in the case of an Image) can be performed.
 //##
 //## For more information on related classes, see \ref Geometry.
 //##
 //## Geometry3D instances referring to an Image need a slightly
 //## different definition of corners, see SetImageGeometry. This
 //## is usualy automatically called by Image.
 //##
 //## Geometry3D have to be initialized in the method GenerateOutputInformation() 
 //## of BaseProcess (or CopyInformation/ UpdateOutputInformation of BaseData, 
 //## if possible, e.g., by analyzing pic tags in Image) subclasses. See also
 //## itk::ProcessObject::GenerateOutputInformation(),
 //## itk::DataObject::CopyInformation() and
 //## itk::DataObject::UpdateOutputInformation().
 //## 
 //## Rule: everything is in mm (ms) if not stated otherwise.
