BUG: disable computation of fixed image gradients in ANTS metric

itkANTSNeighborhoodCorrelationImageToImageMetricv4
Image gradients were being calculated unnecessarily for the
fixed image. Changed behavior to mimic base class which
calculates image gradients according to baseclass option
for image gradient source.

PERF: CompositeTransform - use raw pointers for efficiency

Increase efficicency in several CompositeTransorm methods that
are used in tight loops. Previously a smart pointer was
returned by value, requiring object register/unregister.

BUG: Add TimeVaryingBSplineVelocityFieldTransform to wrapping exclusion.

This allows one of Gaetan's nice quality control tests to pass.  Since
TimeVaryingVelocityFieldTransform is excluded, I assume that this class should
be excluded, too.

BUG: yet still more debugging for itkSimpleImageRegistrationTest

Changes to get more debug output in succesful runs of
itkSimpleImageRegistrationTest3, for comparison on builds that
fail for the main test.

BUG: Rename and fix v4 Demons metric to MeansSquares

The implementation in itkDemonsImageToImageMetricv4 was
actually of a MeanSquares metric. Rename the class and
make small changes to match MeanSquaresImageToImageMetric.

COMP: attributes don't do anything in forward declarations

The export macro has been removed from the forward declaration which

COMP: Use SizeValueType for indexing in Neighborhoods

Converted the NeighborIndexType to SizeValueType.

Conversion from SizeValueType to unsigned int may result in
warning. Additionally, the usage of int for indexing and sizes is
limiting. This also makes the indexing type consistent with the
ImageContainers.
