This is using the C++11 override keyword to make the compiler check to
ensure that we are correctly overriding virtual methods when we mean to.
Currently this will not compile without C++11. However, we are planning
on moving to C++11 very soon, and we can fix the macro if we don't.

The VTKM_SUPPRESS_EXEC_WARNINGS should go before the template keyword,
but on a couple of methods in FunctionInterfaceDetailPre.h.in it was
after the template keyword.
Add pragmas to disable warnings 4244 and 4800 on Visual Studio when
compiling third party libraries. This gets around some warnings inside
the thrust library.
This is a little tricky since they don't seem to have considered that
you will have files in both the source and build directory or that the
file locations will not match exactly with the install locations.
The test is a simple CMake script that finds all files in the build
directory with certain extensions (.h, .cxx, etc.) and makes sure that
the filename is listed somewhere in the CMakeLists.txt file of the same
directory. If the filename is listed in the CMakeLists.txt file, then
there is a good chance it is being addressed by the build.
This should help catch when header files are not being installed. It also
should help verify that test builds are being done on all files. It will
also highlight dead source files.
MSVC has a warning for using "unsafe" algorithms such as fill_n that can
easily overrun the end of unchecked pointers. The problem is that there
are lots of valid uses of these algorithms, and the signal that this is
a valid use is MSVC-specific. Even less fortunate is the fact that if
another header violates the warning, it is impossible to suppress it
because it happens in a system header file (xutility), which was included
far before the actual offending code occured. Even less fortunate than
that, a boost header we (indirectly) use sets off this warning, cannot
be suppressed, and is not going to be fixed
(https://svn.boost.org/trac/boost/ticket/11426). The best solution is to
turn off this problematic warning for everybody.
These asserts are consolidated into the unified Assert.h. Also made some
minor edits to add asserts where appropriate and a little bit of
reconfiguring as found.
We are disabling the entire vectorization hints for ICC as it generates
both bad code, and dramatically decreases compile time.
The compiler does not check for aliasing or dependencies that might cause
incorrect results after vectorization, and it does not protect against illegal
memory references. #pragma ivdep overrides potential dependencies, but the
compiler still performs a dependency analysis, and will not vectorize if it
finds a proven dependency that would affect results. With #pragma simd, the
compiler does no such analysis, and tries to vectorize regardless.
As part of the work to reduce the number of copies of array handles the CUDA
backend was broken. The transportation of stack allocated classes to CUDA
relies on all member variables being value based, not references/pointers.
This correct the issue of sending references to host side memory to CUDA, at
the cost of two copies of the Invocation object.
When we move to C++11 we need to revisit this work and see if std::move
can help reduce the cost of these copies.

There was an inconsistency in naming classes where axes-aligned grids
with even spacing were sometimes called "uniform" and sometimes called
"regular". Maintain consistency by always calling them uniform.

It used to be possible for vtk-m to say it was multiple compilers, for example
it could be both GCC and PGI, Clang and MSVC ( yes possible ), or Intel and
Clang.
This logical restructure now makes that impossible, and instead prefers a system
where we choose the most specialized version of the compiler over the most
general, where general is GCC / Clang.
Older GCC compilers (earlier than 4.6) do not support the diagnostic
pragmas that push and pop the warning levels. This change just disables
the warnings we need to for third party libraries and leaves them off.
This means you might miss some legit warnings on older compilers, but
most developers use newer compilers anyway, and the push/pop should
still work there.
Scatter in worklets
Add the functionality to perform a scatter operation from input to output in a worklet invocation. This allows you to, for example, specify a variable amount of outputs generated for each input.

This has been requested on the mailing list to make it easier to
interpolate integer vectors.
There are a couple of downsides to this addition. First, it implicitly
casts doubles back to whatever the vector type is, which can cause a
loss of precision. Second, it makes it more likely to get overload
errors when multiplying with Vec. In particular, the operator to cast
Vec of size 1 to the component class had to be removed.
