Merge-request: !929

TBB's ReduceByKey was using the generic DeviceAdapterGeneral
implementation and was about 50x slower than the serial implementation,
which is very efficient.

This patch improves TBB's RBK implementation significantly, though it still
does not scale well. On a quad core processor, this implementation performs
comparably or slightly worse than the highly efficient serial algorithm.
More than 4 cores may be needed to see sufficient parallel speedup that
would overcome the TBB overhead, and grain size does not seem to affect the
performance significantly.

 Add 'N-dimensional histogram, histogram marginalization and entropy calculation worklets and filters'
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !847

Added an overloaded version of vtkm::worklet::Threshold::Run that takes
a dynamic cell set instead of a concrete cell set type. This is
implemented by basically moving the CastAndCall from the Threshold
filter to the worklet class. This allows other filters (that might have
similar operations with different predicates) to use the same code. (It
also happens to grately simplify an example for the User's Guide I am
working on.)

Once cell sets use virtual methods, we should be able to collapse code
like this quite a bit anyway.

 Make Get/SetActiveCellSetIndex method names match in filter
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !923

The filter classes have an internal CellSetIndex member that tracks on
which cell set to operate on. The get accessor is called
GetActiveCellSetIndex (note the descriptive "Index" at the end of the
function name). However, the set accessor was called SetActiveCellSet
(sans "Index"). This discrepancy does not make a lot of sense.

This commit changes SetActiveCellSet to SetActiveCellSetIndex. Not only
do I like the extra descriptor (in case we later want to set cells by
name), it is also used much less than the get method so is less
disruptive.
