When you create a CellSetPermutation you provide an array of the cell ids that
you want to iterate. This allows the user to do custom blanking of a data set,
or to do multi iteration over a set of cells.
The functions for doing interpolations and derivatives were called
CellInterpolate and CellDerivative, but the file names were
Interpolate.h and Derivative. Now the files are CellInterpolate.h and
CellDerivative.h so they are more consistent and a bit easier to find.
The interpolate and derivative functions has the shape tag at end of the
function arguments (just before the "worklet" parameter, which is just
the error handling mechanism). However, the parametric coordinate
functions had the shape tag at the beginning. Moved the shape tag to the
end to be more consistent within these functions and also in other uses
throughtout VTK-m.
This class was used to store a group of from field data in a topology
map. However, the fetching has been changed to use a customized class
for each type of fetch that can be optimized for the fetch type and does
not require to know the number of items in the fetch at compile time.
Thus, this class is no longer needed, so it is being removed.
Previously there was a Connectivity* structure for both the control
environment and the execution environment. This was necessary before
because the connectivity is explicit to the from and to topology
elements, so you would get this structure from the appropriate call to
CellSet*. However, the symantics are changed so that the type of
connectivity is selected in the worklet's dispatcher. Thus, it is now
much cleaner to manage the CellSet structure in the CellSet class itself
and just have a single set of Connectivity* classes in the execution
environment.
Some fixes to VertexClustering
VertexClustering previously only worked with data of a specific floating
point type (32 bit for point coordinates). Add some templates to accept
either 32 bit or 64 bit floating points for point coordintes and be a
bit more careful about implicit type conversions.
I also made some changes to conform better with the VTK-m coding
standards. The most common changes are using 2 space indentation for all
block levels, capitolizing and using camel case for all class members,
and prefixing "this->" to all use of internal class members.

This is built ontop of the ExecutionObjectBase work, and is designed to show
other developers how they can create custom objects that are shared among
all worklets, but are passed as parameters to the worklet.
This includes changing methods like LoadDataForInput to PrepareForInput.
It also changed the interface a bit to save a reference to the storage
object. (Maybe it would be better to save a pointer?) These changes also
extend up to the ArrayManagerExecution class, so it can effect device
adapter implementations.
The Fetch class is responsible for moving data in and out of some
collection in the execution environment. The Fetch class is templated
with a pair of tags (the type of fetch and the aspect) that control the
mechanism used for the fetch.
The Transport class is responsible for moving data from the control
environment to the execution environment. (Actually, it might be more
accurate to say it gets the execution environment associated with a
given control object.) The Transport class is templated with a tag that
controls the mechanism used for the transport.
Whenever creating a functor to be launched in the execution environment
using the device adapter Schedule algorithm, you had to also create a
couple of methods to handle error message buffers. For convenience, lots
of code started to just inherit from WorkletBase. Although this worked,
it was a misnomer (and might cause problems in the future if worklets
later require different things from its base). To get around this
problem, add a FunctorBase class that is intended to be used as the
superclass to functors called with Schedule.
