This patch adds support for reading and writing NIFTI files, as well
as full access to the NIFTI header.  Versions 1 and 2 of the NIFTI
header are supported, and the reader can also be used to read Analyze 7.5
files, though the only Analyze header elements that are supported are the
ones that overlap with NIFTI.  Automatic compression and expansion for
gzipped files is also provided whenever the filename ends with a .gz
extension.

Many of the Widget tests supply in-code event logs. This patch adds
an additional option to vtkTesting::InteractorEventLoop. The new
option, --PlaybackFile, supplies a file name for the
InteractionRecorder. This allows tests to modify the playback
events without changing the source code for the test. This separates
changes to the playback events from changes to the test code.

A couple of tests have been modified to illustrate the usage of the
InteractorEventLoop.

In the future, the current widget tests should be changed to use the
InteractionEventLoop rather than ifdef'ed code for playing and
recording.

vtkPStreamTracer was causing the creation of a new locator at
every iteration (task), which is very slow for cell locators
since they have to bin data every time. Fixed by removing
the reallocation and using one locator. The input data does not
change between iterations so recreationg the locator was totally
unnecessary.

94f12816 ExternalData: Add backtrace to missing file warning

33920cf2 BUGFIX: Add guards for NULL ivars in PrintSelf

cd0b6e68 Set MACOSX_RPATH property default consistently across CMake versions

The PrintSelf method of vtkStructuredImplicitConnectivity
was causing failures in the otherPrint test b/c it was
dereferencing NULL ivars. Fixed that by adding guards
to chekc if the ivars are NULL.

Since commit 32e48028 (If the original file is missing, make it
non-fatal, 2013-10-31) we use a STATUS message instead of a FATAL_ERROR
to report that a DATA{} reference names a missing file.  The STATUS
message has no backtrace.  Use an AUTHOR_WARNING message instead.

Also restore the FATAL_ERROR message when the DATA{} reference names a
file that exists as a directory.

The MACOSX_RPATH target property was introduced in CMake 2.8.12, but we
currently allow CMake 2.8.8.  Set CMAKE_MACOSX_RPATH to 0 by default
so that we get consistent behavior across all versions of CMake.
Leave a comment explaining when the default should be updated.

Now that we set a MACOSX_RPATH default explicitly, we no longer need to
set CMake Policy CMP0042 as was added in commit 2ad9f474 (Set CMake
Policies CMP0025 and CMP0042 as necessary, 2014-03-11), so remove it.

f41f521f BUGFIX: Fix integer overflow in vtkStructuredData
271954af ENH: DuplicateNodes property to RCB partitioners

This commit introduces the vtkStructuredImplicitConnectivity class, intended
as a lower-level helper that provides functionality for resolving
situations where "gaps" are present in a distributed structured dataset. Gaps
are resolved by communicating the data (growing the grid to the right) as
necessary to close the gap. This situation is common with finite difference
grids that are partitioned with respect to the nodes of the grid, or when some
other post-processing filter, e.g., sampling the grid to reduce the resolution
introduces a gap.The present implementation requires one grid per process and
can deal with 2-D datasets -- XY,XZ,YZ -- as well as 3-D datasets. A test for
all 2-D and 3-D cases is also added.

c05001df Use vtkMPI.cmake helper for all module MPI tests

In commit cd4fc15a (Rewrite the testing macros, 2014-03-14)
the vtk_test_mpi_executable() helper was introduced to add
MPI tests.  It depends on the vtk_mpi_link() helper in the
vtkMPI module.  Include the latter in all test CMakeLists.txt
files that add MPI tests.

VTK module archive libraries are installed as part of the "Development"

Before this commit, vtkRCalculatorFilter produced the same type
of output as its input.  This is no longer the case.  For example,
you can now run an R script that takes one table as input
and produces two trees as output.  A test is included for this
new functionality.

This commit also makes vtkRAdapter::RToVTKTree() more robust.
Previously, we assumed that the elements in the R Tree would
appear in a certain order, but apparently that is not guaranteed
to be true.  We now parse these elements in whatever order they
appear.  While I was modifying this function, I also cleaned it up
so it should now adhere to VTK's coding style.
