Reading Arbitrary Transforms, Compute Something if Linear

I think the 2D vs 3D instantiation can be solved by templating over dimension.

For determining type, maybe this example would help?

  using ReadCompositeTransformType =
    itk::CompositeTransform<ReadScalarType, Dimension>;
  auto it = transforms->begin();
  if (!strcmp((*it)->GetNameOfClass(), "CompositeTransform"))
  {
    ReadCompositeTransformType::Pointer compositeRead =
      static_cast<ReadCompositeTransformType *>((*it).GetPointer());
    compositeRead->Print(std::cout);
  }
