-Changing the existing CellLocator.h to CellLocatorHelper.h,
it's used by CellLocatorTwoLevelUniformGrid.h
-Changing unit tests and worklets that use CellLocator.h to use CellLocatorHelper.h
This commit adds a worklet and a filter to compute
signed integral measures of cells.
It also begins the practic of adding a markdown
changelog entry in `doc/changelog`. See the
changelog entry for details.

It takes CellSetStructured<2> and DynamicArrayHandle and uses CastAndCall
to resolve data type for pixels. Moved implementation to the RunImpl
function object.
ImageConnectivity worklet implements a parallel connected component
labeling algorithm for 2D structured grids/images. For each pixel,
it search for the pixel's 6 neighbors and classify them as the
same connected component if their corresponding "color" field have
the same value.
Previously, when a Worklet needed a scatter, the scatter object was
stored in the Worklet object. That was problematic because that means
the Scatter, which is a control object, was shoved into the execution
environment.
To prevent that, move the Scatter into the Dispatcher object. The
worklet still declares a ScatterType alias, but no longer has a
GetScatter method. Instead, the Dispatcher now takes a Scatter object in
its constructor. If using the default scatter (ScatterIdentity), the
default constructor is used. If using another type of Scatter that
requires data to set up its state, then the caller of the worklet needs
to provide that to the dispatcher. For convenience, worklets are
encouraged to have a MakeScatter method to help construct a proper
scatter object.
- PushOutOfDomain would loop over without exiting indefinately utilizing all max steps.
It's supposed to execute only once the particle goes out of spatio-temporal boundary.
- Removing the check for the steamlines polyline points to be same as the maxSteps from
the unit test, as if the particle has already taken some steps, then the polyline
points written out will always be lower than the total number of steps taken by the
current node.
- Adding code to support taking short steps (minimize boundary errors)
- Adding time of advection to the particle from the Integrator
- API changes for TakeStep
- TakeStep should only care about the maximum steps as it's a field on a Particle
- The check for out of temporal and spatial bounds has been moved to the Worklet
- Changing some of the internal APIs for supporting these new features/fixes
- Changing inheritance in the Integrators class to be more obvious than something convoluted
In some of the tests there was a field that was using a counting array.
This uses an integer as the value type and has a special implicit
storage type. Currently, this is likely to cause problems whenever it
runs into a cast and call of a dynamic array. For now, let's avoid
these.
In the near future we should have expanded virtual method capabilities
that will make it possible to support these atypical arrays.

Filters now support executing on a dataset to produce a result dataset
with automatic mapping of fields to the output dataset. Fields to map
can be selected using `vtkm::filter::FieldSelection` class, which provides
constructors to map all or no fields, along with a selection of fields.
This updates all tests to use the new filter API.

The ScalarsToColors is the first step in reproducing the color
capability that exists in VTK. The next step after this is to
provide a comparable lookup table.
1. Add option to copy user supplied array in make_ArrayHandle.
2. Replace Field constructors that take user supplied arrays with make_Field.
3. Replace CoordinateSystem constructors that take user supplied arrays with
make_CoordinateSystem.
Rob noticed a degridation in performance in some worklet tests when
ArrayCopy was added. I hypothesize that this slowdown is doing the array
copy with TBB instead of serial in the serial tests. (There have been
some checks in the existing code to suggest that some operations in TBB
can be slower than serial.) This change forces the array copy to be on
the device for which we are testing.
Sandia National Laboratories recently changed management from the

The AverageByKey.h header file had a single function that used the
device adapter algorithm ReduceByKey method to do a simple averaging of
a field. I added a second method that can do an average when given a
vtkm::worklet::Keys object. I expect this to be a common use case as we
implement transforming fields from input to output in many algorithms.

PolyData (0D, 1D, and 2D) cells to the output. The external

Added tests to the external faces filter and worklet.
Alas, VS 2013 will keep us from using "using" to declare function
signatures. Reverting to typedef until we bump our MSVC requirement.
This appears to be a compiler bug:

All types of cell sets should have a consistent interface. This is
tested (and fixed) for explicit and permutation cell sets. However, an
unfixed bug that has been identified is that permutation cell sets only
work for point to cell topologies. All others are not supported
correctly.

MSVC does not allow typename for non templated types while
compiling with c++98 std. (clang/gcc allow it)
Don't know about which standards Kitware uses to test builds, but
this should fix it.
Also removing unused parameter from the particle advection example.
Created ParticleAdvection.h for worklets that match the worklet pattern.
Slight reorganization of existing code to match this pattern.
Added a unittest particle advection.
VTK expects that the tensor fields generated by the gradient of a vector field
to have FORTRAN ordering instead of C ordering.
Discovering this actually uncovered bugs in the Vorticity and QCriterion
implementation where they presumed FORTRAN ordering, and would generate
incorrect results.
Basically we can run the gradient worklet and compute the Divergence, Vorticity,
and QCriterion without ever having to store the gradient tensor in global memory
The gradient worklet is now templated on the input value type. This simplifies
the logic of the gradient. Secondly we have added a Run method for the
first step of making gradient a 'fatter' worklet that can handle generation
of vorticity, Divergence, and QCriterion.
