Xcode 7 warnings
The XCode 7 compiler has a new warning for unused typedefs. The Boost code we use has some instances where this warning gets issued. Suppress these warnings.
See merge request !199
This is to be used in place of BOOST_STATIC_ASSERT so that we can
control its implementation.
The implementation is designed to fix the issue where the latest XCode
clang compiler gives a warning about a unused typedefs when the boost
static assert is used within a function. (This warning also happens when
using the C++11 static_assert keyword.) You can suppress this warning
with _Pragma commands, but _Pragma commands inside a block is not
supported in GCC. The implementation of VTKM_STATIC_ASSERT handles all
current cases.

The boost assert macros seem to have an issue where they define an
unused typedef. This is causing the XCode 7 compiler to issue a warning.
Since the offending code is in a macro, the warning is identified with
the VTK-m header even though the code is in boost. To get around this,
wrap all uses of the boost assert that is causing the warning in the
third party pre/post macros to disable the warning.
Performance testing has shown that the combined lower-bounds + update-connectivity
worklet is marginally, but consistently faster than DeviceAdapterAlgorithm::LowerBounds
followed by an update-connectivity worklet. It also requires less memory.
Template the splatter algorithm over Kernel type and use abstract kernel
interface to fetch the kernel value.
Add Gaussian, Spline3rdOrder kernel classes templated over dimension.
Other kernels can/will be added in future.
Kernel classes are defined such that the integral of the volume is unity
as is the convention in (for example) SPH simulations.
Clean up the implementation to take a uniform grid dataset as input
and splat using the correct world coordinates of the points into
the volume. Kernels are centred around the splat points in world coordinates
(floating point) and not quantized to the nearest voxel.
Skip the generation of all volume points which is unnecessary (memory usage).
Add ability to specify a radius array with one entry per splat point so
that the size of each splat may be controlled arbitrarily.
Although this is labeled as a unit test, this is more of an integration
test to make sure that when a uniform point coordinate is passed as a
field to a WorkletTopologyMap from points to cells with a regular cell
set, you get the specialized VecRectilinearPointCoordinates in the
worklet argument.
adding cell-to-point topology support and worklet
This adds code to support a cell-to-point topological mapping worklet.
For explicit cell set, there is code to calculate a cell-to-point topology from the canonical point-to-cell topology. (It is not parallelized at this point.) Most of the required code for structured grids was already in place.
