The check to determine the version of VTK-m from git was duplicated in
CMakeLists.txt. Although pointless, it generally was not a big deal
(only an extra check when running CMake). Except for some reason with
the latest changes to the CMake build the second time find_package(Git)
was called on my system the GIT_EXECUTABLE variable got cleared out and
that caused the configure to fail. I have no idea why this happens (and
running CMake again seems to fix the problem), but simply removing the
extraneous find seems fix the problem.
Removing another API that need not be on MultiBlock. There's generally
no need for apps to know this. If needed, we can add `...Compute`
function. This removes another API on MultiBlock that could trigger
parallel communication/synchronization.
Removing MultiBlock::GetGlobalRange API to keep things consistent with
DataSet API. Instead, one should use `FieldRangeCompute` or
`FieldRangeGlobalCompute` as appropriate.

When using the GNU header files on a system, the icc compiler emulates
the behavior of the gcc compiler on the system. (See https://
software.intel.com/en-us/node/522750) This appears to mean that icc
features that are not available in gcc could get turned off. In
particular, we found that the __assume feature stopped working.
To get around this problem, do not use __assume when compiling with icc
and __GNUC__ is defined. Instead, use the available gcc features.
Previously memory that was allocated outside of VTK-m was impossible to transfer to
VTK-m as we didn't know how to free it. By extending the ArrayHandle constructors
to support a Storage object that is being moved, we can clearly express that
the ArrayHandle now owns memory it didn't allocate.
Here is an example of how this is done:
```cpp
T* buffer = new T[100];
auto user_free_function = [](void* ptr) { delete[] static_cast<T*>(ptr); };
vtkm::cont::internal::Storage<T, vtkm::cont::StorageTagBasic>
storage(buffer, 100, user_free_function);
vtkm::cont::ArrayHandle<T> arrayHandle(std::move(storage));
```
This fixes the three following issues with StorageBasic.
1. Memory that was allocated by VTK-m and Stolen by the user needed the
proper free function called which is generally StorageBasicAllocator::deallocate.
But that was hard for the user to hold onto. So now we provide a function
pointer to the correct free function.
2. Memory that was allocated outside of VTK-m was impossible to transfer to
VTK-m as we didn't know how to free it. This is now resolved by allowing the
user to specify a free function to be called on release.
3. When the CUDA backend allocates memory for an ArrayHandle that has no
control representation, and the location we are running on supports concurrent
managed access we want to specify that cuda managed memory as also the host memory.
This requires that StorageBasic be able to call an arbitrary new delete function
which is chosen at runtime.
Previously types such as vtkm::Id or vtkm::U/Int32 would be cast to whatever
the weight type was. This is problematic as they should actually be casted to
a double type as the weight type could be a float and therefore the results
This commit removes `vtkm::filter::Result`. All methods that used
`vtkm::filter::Result` simply change to use `vtkm::cont::Dataset` instead.
The utility API on `Result` that was used to add fields to the resulting
dataset is now available via `vtkm::filter::internal::CreateResult`.
Adding a new exception type `vtkm::cont::ErrorFilterExecution`. Unlike
existing exceptions, when thrown in `TryExecute`, this exception causes
the call to not attempt to execute on any other devices and let it be
thrown so that the application can catch it.

Changed the "default" ColorTable preset from "cool to warm" to
"viridis." Also made a default constructor for ColorTable that sets it
to this default preset.
The main reason to change to viridis for the default is that it is in
LAB space. We are concerned that having the default ColorTable preset
being Diverging space could lead to users using that color space
inappropriately.
The problem is that there is no good "default" constructor for
ColorTable. The previous default constructor created an empty color
table, but that would be confusing if someone actually tried to use it.
We could set ot to the default preset, but the default preset uses the
diverging color map, which could foul people up if they actually want to
edit or create their own color map. Instead, force the declaration of
ColorTable to indicate what you plan to do with it.
You can still select presets through strings (and we leave ourselves
open to add more presets through strings than enumerating with the
enum), but this provides a way to select a preset that is verified by
the compiler.
Previously there was a special build for the template source files
(.hxx) that installed them but did not create the test builds (because
they cannot be built outside of their enclosing .h file). It also added
an entry into the IDE that let them show up on the file list. However,
because they were not explicitly built as part of something actually
compiled, they did not have an compile options associated with them.
This caused confusion in some IDEs where it could not find the header
files it included, which made it more frustrating to edit them.
