Exodus readers and writers no longer support packing and unpacking
of model meta data so I removed all of the unnecessary code.

Adding a new test for TestSocketCommunicator.

Add a tests for vtkSocketCommunicator. Also added a driver (vtkTestDriver)
that can be used when adding tests that need to run multiple executables.
Currently vtkTestDriver is simple: it simply spawn executables with commandlines
specified.

Also made some const correctness improvements,
which cascaded to clients of this class.

Other misc cleanup too.
