-// WARNING TODO CLEANME
-// Actual limitations of this code:
-//
-// /////// Redundant and unnecessary header parsing
-// In it's current state this code actually parses three times the Dicom
-// header of a file before the corresponding image gets loaded in the
-// ad-hoc vtkData !
-// Here is the process:
-// 1/ First loading happens in ExecuteInformation which in order to
-// positionate the vtk extents calls CheckFileCoherence. The purpose
-// of CheckFileCoherence is to make sure all the images in the future
-// stack are "homogenous" (same size, same representation...). This
-// can only be achieved by parsing all the Dicom headers...
-// 2/ ExecuteData is then responsible for the next two loadings:
-// 2a/ ExecuteData calls AllocateOutputData that in turn seems to
-// (indirectely call) ExecuteInformation which ends up in a second
-// header parsing
-// This is fixed by adding a test at the beginning of ExecuteInformation
-// on the modification of the object instance. If a modification have been
-// made (method Modified() ), the MTime value is increased. The fileTime
-// is compared to this new value to find a modification in the class
-// parameters
-// 2b/ the core of ExecuteData then needs gdcmFile (which in turns
-// initialises gdcmHeader in the constructor) in order to access
-// the data-image.
-//
-// Possible solution:
-// maintain a list of gdcmFiles (created by say ExecuteInformation) created
-// once and for all accross the life of vtkGdcmHeader (it would only load
-// new gdcmFile if the user changes the list). ExecuteData would then use
-// those gdcmFile and hence avoid calling the construtor:
-// - advantage: the header of the files would only be parser once.
-// - drawback: once execute information is called (i.e. on creation of
-// a vtkGdcmHeader) the gdcmFile structure is loaded in memory.
-// The average size of a gdcmHeader being of 100Ko, is one
-// loads 10 stacks of images with say 200 images each, you
-// end-up with a loss of 200Mo...
-//
-// /////// Never unallocated memory:
-// ExecuteData allocates space for the pixel data [which will get pointed
-// by the vtkPointData() through the call
-// data->GetPointData()->GetScalars()->SetVoidArray(mem, StackNumPixels, 0);]
-// This data is never "freed" neither in the destructor nor when the
-// filename list is extended, ExecuteData is called a second (or third)
-// time...
