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.
See merge request !64
When mixing precision, it is possible for the computation to pick a grid
size greater than the requested number of dimensions. This change
ensures that you never get more dimensions than requested. (Thanks to
Chun-Ming Chen for the fix.)
The test now behaves the same way as it did before the last change.

Implement a way to pass a portal to worklet as a parameter.
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.

The VTKM_MSVC is just defined if using MSVC. It is not set to any value.
There was a reference in Math.h that assumed it was set to true, which
it was not. This simple change should fix that.
Math
Adds a set of portable math functions, most of which are "expected" to be available and are typically useful. They include things like trigonometry (sin, cos, tan, etc.), floating point information (nan, finite, etc), and min/max.

Also fix some issues that caused the compile to fail when trying to
run some of the math functions on a CUDA device. In particular, CUDA
is picky about using a global const on a device when the const type is
not one of the basic C types.
By mistake the cuda texture memory load code was not being used, so correct
that issue and allow loading of vtkm::Vec and primitive types. Currently
the only issue is loading int8/int16 uint8/uint16 through texture memory.
Fix Parallel Scan implementation for TBB Device
The previous implementation assumed the identity value to be zero, which does
not work for multiplication. Changed the interface to require an initial value
for Exclusive Scan with custom operator (TBB Device only, for now).
