d6f66d17a3 Testing run methods now take argc/argv to init logging/runtime device 
`vtkm::cont::testing` now initializes with logging enabled and support
for device being passed on the command line, `vtkm::testing` only
enables logging.

024a75821d Make DeviceAdapterId constructor protected. 
This forces users to use a defined tag, since they shouldn't need
to create their own.

554bc3d369 At runtime TryExecute supports a specific deviceId to execute on.

can be told which device at runtime to use.

91df123055 Remove VTKM_EXEC modifiers from CPU devices 
Having VTKM_EXEC on algorithms for CPU devices was problematic because
the algorithms were specific to the CPU, but during a CUDA compile it
would try to compile device code (for no reasons since it was never
called on a device).

Remove these identifiers for the idea that a device implementation knows
specifically what function modifiers to use and does not need the VTK-m
defined catch-alls.

880d8a989e Add vtkm/Geometry.h and test it. 
This commit adds several geometric constructs to vtk-m
in the `vtkm/Geometry.h` header. They may be used from
both the execution and control environments.

We also add methods to perform projection and Gram-Schmidt
orthonormalization to `vtkm/VectorAnalysis.h`.

See `docs/changelog/geometry.md` included in this commit
for more information.

1c5feeb185 Make sure all device specific tests use the intended device. 
This means that we not only setup the runtime device tracker
to force the intended device, it also means making sure
the default device is the error device.

e28244f345 Re-implement DeviceAdapterRuntimeDetector to avoid ODR violations. 
The previous implementation of DeviceAdapterRuntimeDetector caused
multiple differing definitions of the same class to exist and
was causing the runtime device tracker to report CUDA as disabled
when it actually was enabled.

The ODR was caused by having a default implementation for
DeviceAdapterRuntimeDetector and a specific specialization for
CUDA. If a library had both CUDA and C++ sources it would pick up
both implementations and would have undefined behavior. In general
it would think the CUDA backend was disabled.

To avoid this kind of situation in the future I have reworked VTK-m
so that each device adapter must implement DeviceAdapterRuntimeDetector
for that device.

d77ac2c8dd Don't explicitly set backend on tests that use error backend. 
The per device tests specifically setup the default backend to
be error to smoke out bad uses of the default backend.

944bc3c0d6 Introduce vtkm::cont::ColorTable replacing vtkm::rendering::ColorTable 
The new and improved vtkm::cont::ColorTable provides a more feature complete
color table implementation that is modeled after
vtkDiscretizableColorTransferFunction. This class therefore supports different
color spaces ( rgb, lab, hsv, diverging ) and supports execution across all
device adapters.

705528bf17 vtk-m ArrayHandle + basic storage has an optimized PrepareForDevice method 
By hard coding the PrepareForDevice to know about all the different VTK-m
devices, we can have a single base class do the execution allocation, and not
have that logic repeated in each child class.

By using WrappedBinaryOperator we will not get warnings on vs2017 when
scanning <32bit arrays, and at the same time also properly support
fancy arrays.

825f351d04 Use std::copy in serial Copy implementation. 
I had assumed that the compiler would be clever enough to turn the
iterative implementation of Copy into a memcpy, but inspecting the
disassembly on a release GCC build shows that this is not the case,
likely because it can't assume that the memory ranges do not overlap.

Replacing the loop with std::copy speeds things up (about 30-50%) for
most data types, though there is a slight (usually < 5%) slowdown for
Vec types. The uint8 copy improved by a factor of 8.

Comparison:
