- Added an optimized ProjectPoint2 to CoordinateSystem3D. It has *not* replaced the ProjectPoint method because more tests need to be written. - ProjectPointOntoPlane2 is a faster version of GeometryToolbox::ProjectPointOntoPlane. Same remark as above. - DicomStructureSet.cpp now uses this optimized call.
