DOC: Made AnisotropicDiffusion documentation consistent with code

The documentation for both itkAnisotropicDiffusionFunction.h and
itkAnisotropicDiffusionImageFilter.h listed incorrect guidance for how
to set the m_TimeStep parameter compared with the code.
The documentation is now consistent between the two files and the
code.

BUG: Fix ITK Path test failures

This patch corrects a bug in 706a6bf6e04534c7ea8b98fd9cfbd0dc03b4a596.
Also http://review.source.kitware.com/#/c/9693/

Previously the IncrementInput function in itkPolyLineParametricPath
was not returning the correct offset.

This also deletes the accidental push of the
ExtractOrthogonalSwath2DImageFilterTest.png to the main repository
as well as move the location of the MD5 sum file to migrate away
from Testing/Data.

ENH: Converted Multidimensional splitter to new base class

Ported the old ImageRegionMultidimensional splitter to new
template-less base class.

BUG: When then starting index of the input region was non-zero, the
splitting was erroneous. This is now fixed.
