[vtk-developers] PythonCore module removal

[David Gobbi]

Here's a brief rundown on my gerrit topic that I've pushed for python
wrapping modularization.
(http://review.source.kitware.com/#/t/817/).

The new module will be called "WrappingPython" and will be in the
Python/Wrapping directory.  The new vtkWrappingPython library
replaces the earlier vtkPythonCore library (which was briefly called
vtkWrappingPythonCore).  All the files that were moved from
Wrapping/Python to Wrapping/PythonCore during modularization are
back in Wrapping/Python.

The PythonWrapping module will be turned on whenever WRAP_PYTHON
is on, and is off when WRAP_PYTHON is off.  The CMakeLists.txt for this
module is responsible for building the vtkWrappingPython library, the
vtkpython executable, and the python "vtk" module.

I can do the same for Java, i.e. rename the vtkWrappingJavaCore module
to vtkWrappingJava (but without the version numbers).  This would help
to keep the wrappers consistent.
