STYLE: Remove NULL definition in itkVoronoiDiagram2DGenerator.

We now consistently use ITKNULL_PTR, which is always defined by #include's.

Change-Id: Ied4a9049b7a4a9d9551b63a29555c98c0de97e9d
STYLE: VoronoiDiagram2DGenerator defines a VoronoiDiagramType typedef.

VoronoiDiagramType is more descriptive and informative and follows ITK naming
style than VDMesh.

COMP: Wrap the remaining MeshBase and MeshToMeshFilter types.

Fixes the following:

Wrapping these threw some new wrapping warnings, so this commit fixes those too.

BUG: Demonstrate Inv(Inv(T)) != T

The inverse of the inverse of a transform was not producing parameters
that were consistent with the original.  This patch demonstrates the
problem, and therefore has a failing test.

A subsequent patch adds
inverse->SetFixedParameters(this-GetFixedParameters()) to the
GetInverse(Self *) functions.

BUG: Ensure Inv(Inv(T)) == T for transforms

This patch ensures that the fixed parameters
(i.e. for example the center of rotation) is
preserved during the inverse process.

By doing this, we can ensure that the
Inv(Inv(T)) ~= T for both FixedParameters
and Parameters of a transform.
