CurvatureFlowImageFilter
=========================
- now supports streaming


MultiResolutionImagePyramid
============================
- renamed to MultiResolutionPyramidImageFilter
- it now produces all images at once
  ( the Nth output corresponds to Nth level )
- Set/Get should be consistent now
- PrintSet should be complete now
- Added group PyramidImageFilter to doxygen


New filter:
===========
There is also now a RecursiveMultiResolutionPyramidImageFilter
which uses a fast recursive implementation if the schedule
fits a certain criteria.
