windows.h was only being included for MSVC, while in UnitTestTimer.cxx, the
Windows function Sleep was being called after check for _WIN32. This was
causing compilation failure in MINGW.
Fixes#122
There were some issues for device adapter algorithms (like scan and
reduce) for empty arrays or arrays of size 1. This adds tests for these
short arrays to the device adapter algorithm tests and fixes these
problems.

We previously included windows.h in numerous locations using different
techniques to guard against bringing in parts of the file that are bad
(min/max macros, etc). This solves the problem by consistently using
vtkm/internal/Windows.h to setup everything.
Change the VTKM_CONT_EXPORT to VTKM_CONT. (Likewise for EXEC and
EXEC_CONT.) Remove the inline from these macros so that they can be
applied to everything, including implementations in a library.
Because inline is not declared in these modifies, you have to add the
keyword to functions and methods where the implementation is not inlined
in the class.
First, be more explicit when we mean a range of values in a field or a
spacial bounds. Use the Range and Bounds structs in Field and
CoordinateSystem to make all of this more clear (and reduce a bit of
code as well).
These asserts are consolidated into the unified Assert.h. Also made some
minor edits to add asserts where appropriate and a little bit of
reconfiguring as found.
We have decided that we do not need the concept of an Extent in our data
model. Instead, we simply use dimensions, which can be represented in a
vtkm::Id3.
Even when running with the serial backend, the compiler might enable SIMD
vectorization when optimizations are turned on. When this occurs, we need
to use properly atomic Add's and CAE's.
Previously each device adapter only had a unique string name. This was
not the best when it came to developing data structures to track the status
of a given device at runtime.
This adds in a unique numeric identifier to each device adapter. This will
allow classes to easily create bitmasks / lookup tables for the validity of
devices.
This now allows for even more efficient construction of uniform point
coordinates when running under the 3d scheduler, since we don't need to go
from 3d index to flat index to 3d index, instead we stay in 3d index

When compiling with cuda and tbb enabled in a single translation unit you
need to make sure all try/catch blocks are marked as host only otherwise
the cuda compiler will error out.
Previously it was really hard to verify if a device adapter was valid. Since
you would have to check for the existence of the tag. Now the tag always
exists, but instead you query the traits of the DeviceAdapter to see if
it is a valid adapter.
This makes compiling with multiple backends alot easier.
Robert Maynard tells me that the TBB backend has been tried on versions
of TBB back to 4.0. Since the patch appears to work across them, allow
those versions too.
We have a patched version of TBB's parallel_for.h in our files that
fixes a problem with using std::swap. This issue has since been fixed in
TBB, so for newer versions we should revert back to TBB's
implementation.
On one of my compile platforms, GCC was giving conversion warnings from
any boost include that was not wrapped in pragmas to disable conversion
warnings. To make things easier and more robust, I created a pair of
macros, VTKM_BOOST_PRE_INCLUDE and VTKM_BOOST_POST_INCLUDE, that should
be wrapped around any #include of a boost header file.
tbb includes windows.h, and doesn't use the NOMINMAX so we need to do
that ourselves so that we can use std::min/max and limits<T>::min/max.
At the same we also define WIN32_LEAN_AND_MEAN so that the total number of
macros that windows.h defines is reduced.
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).
