Adds a variable `GlobalPointIndexStart` to `CellSetStructured`.
Adding this to the cell-set, instead of the coordinate system, enables this
feature for different types of datasets like uniform grid, rectilinear, etc.,
with this one change.
The extents can be computed using `GlobalPointIndexStart` and `PointDimensions`.
Did a bit of renaming of the support classes used for
WorkletPointNeighborhood. First, the OnBoundary tag is changed to
Boundary to match other tags and reflect some changes in the resulting
methods. Also moved the BoundaryState and Neighborhood classes from
vtkm::exec::arg to vtkm::exec to be more accessible. Finally, the
Neighborhood class name was changed to FieldNeighborhood to be more
specific on what role this class plays with neighborhood.
Previously, WorkletPointNeighborhood had a template argument to select
the size of the neighborhood. This change removes that template
argument. Instead, the vtkm::exec::arg::BoundaryState methods now take
in a size parameter when determining when it overlaps the boundary.
If in the future we want to add the ability to select the neighborhood
size at compile-time (for performance reasons), I suggest adding this
template argument to the OnBoundary tag for ExecutionSignature.
Previously, vtkm::exec::arg::BoundaryState only provided methods that
said whether or not the neighborhood extened past the boundary of a
mesh. That is fine for a 3x3x3 neighborhood, which can only extend over
the boundary by one. However, that is problematic for larger
neighborhoods where you may need to know how far neighborhood extends
over the boundary.
This changes allows you to query how far the neighborhood extends within
the constrains of the boundary.

This is a subclass of ExecutionObject and a superset of its
functionality. In addition to having a PrepareForExecution method, it
also has a PrepareForControl method that gets an object appropriate for
the control environment. This is helpful for situations where you need
code to work in both environments, such as the functor in an
ArrayHandleTransform.
Also added several runtime checks for execution objects and execution
and cotnrol objects.

1. Have a per-thread pinned array for cuda errors
2. Check for errors before scheduling new tasks and at explicit sync points
3. Remove explicit synchronizations from most places
Addresses part 2 of #168
There was an error in TestingPointLocatorUniformGrid in which it was
creating arrays of type vtkm::Float32 and passing them to a worklet that
expected vtkm::FloatDefault. This is corrected.
- Reducing the stack allocation for CUDA for the BIH unit test
- Adding changes from Ken's review
- Suppress ptxas stack size warning for BoundingIntervalHierarchy
The vtkm::exec::PointLocatorUniformGrid has a default constructor. It
was "helpfully" declared as VTKM_EXEC_CONT, but apparently that is the
wrong thing to do for constructors that are set to default.
Previously when PointLocatorUniformGrid.h was compiled by the CUDA
compiler, the compiler would crash. Apparently during the ptxas
part of the compiler goes into a crazy recursion and runs out of
stack space. This appears to be a long-standing bug in CUDA
(been there for multiple releases) without a clear reason why it
sometimes rears its ugly head. (See for example
https://devtalk.nvidia.com/default/topic/1028825/cuda-programming-and-performance/-ptxas-died-with-status-0xc00000fd-stack_overflow-/)
The problem appears to be when having a doubly or triply nested
loop over a box of values to check in the uniform array. This
appears to fix the problem by converting that to a single for
loop with some index magic to convert that to 3D indices.
Vec class objects can now be constructed during compile-time
as constant expressions by calling Vec( T, ... ) constructors
or through brace-initialization.
Constant expression using fill constructor and nested vectors
of sizes greater than 4 are not supported yet.
Changes made to WrappedOperators.h for resolving overload
ambiguities in Vec construction and typecasting.
Appropriate test cases were added to UnitTestTypes.cxx.
Addresses issue #199.

There was a direct edit to WorkletInvokeFunctorDetail.h that was not
reflected in WorkletInvokeFunctorDetail.h.in. This makes the two files
consistent so that future edits will not loose the changes.
