Using v0+w*(v1-v0) can be numerically unstaqble due to floating point
arithmatic errors.  Additionaly, the newer form also resolves type
conversion warnings.

The intel compiler generates internal compiler errors when you use
pragma simd and haven't defined NDEBUG.

We have found that ICC 14.0 produces bad simd code that causes
vtkm worklets to throw SIGBUS signals. This issue was resolved in
ICC 15.0

Previously we hinted to the compiler that it should vectorized operations
where the input and output are the same array. This obviously caused problems,
and these hints had to be removed.

In the future we need to first check for aliased arrays, and go from there.

Now it is clear you pass in the input range and you will get the output
range

Now it is clear you pass in the input range and you will get the output
range.

The previous code would over allocate all the scatter arrays since
it was computing the output range, than using that as the input range.

When vectorization is enabled we start using 'fast' math, and therefore instead
of getting perfect 0.0 values we get values that are extremely close to zero.

Even when running with the serial backend, the compiler might enable SIMD
vectorization when optimizations are turned on. When this occurs, we need
to use properly atomic Add's and CAE's.

When the number of parameters to a worklet hits 6+ like the EdgeGenerate
worklet did, the compile times when some of those parameters are dynamic array
handle is very bad.

For example when building the MarchingCubes filter for VTK integration the
EdgeGenerate worklet would take 800+ seconds to compile, but when we switch
it to have fewer arguments the compile time comes down to ~250sec.

This way we have an example of how to use the filter code.

The original name was a really bad name, so thank to Ken for suggesting
a better name.

The original implementation wasn't flexible enough to handle the requirements
that filter requires ( mainly policy support ).

This isn't needed now that vtkm::cont::Field can compute bounds.
