Files
	CpuTimer.h
	A simple timing class (in case openvdb::util::CpuTimer is unavailable)
	CreateNanoGrid.h
	Convert any grid to a nanovdb grid of the same type, e.g. float->float.
	CSampleFromVoxels.h
	DitherLUT.h
	Defines look up table to do dithering of 8^3 leaf nodes.
	ForEach.h
	A unified wrapper for tbb::parallel_for and a naive std::thread fallback.
	GridBuilder.h
	This file defines a minimum set of tree nodes and tools that can be used (instead of OpenVDB) to build nanovdb grids on the CPU.
	GridChecksum.h
	Computes a pair of 32bit checksums, of a Grid, by means of Cyclic Redundancy Check (CRC)
	GridHandle.h
	Defines GridHandle, which manages a host, and possibly a device, memory buffer containing one or more NanoVDB grids.
	GridStats.h
	Re-computes min/max/avg/var/bbox information for each node in a pre-existing NanoVDB grid.
	GridValidator.h
	Checks the validity of an existing NanoVDB grid.
	HDDA.h
	Hierarchical Digital Differential Analyzers specialized for VDB.
	HostBuffer.h
	HostBuffer - a buffer that contains a shared or private bump pool to either externally or internally managed host memory.
	Invoke.h
	A unified wrapper for tbb::parallel_invoke and a naive std::thread analog.
	IO.h
	NanoToOpenVDB.h
	This class will deserialize an NanoVDB grid into an OpenVDB grid.
	NodeManager.h
	This class allows for sequential access to nodes in a NanoVDB tree on both the host and device.
	OpenToNanoVDB.h
	PrefixSum.h
	Multi-threaded implementations of inclusive prefix sum.
	Primitives.h
	Generates volumetric primitives, e.g. sphere, torus etc, as NanoVDB grid.
	Range.h
	Custom Range class that is compatible with the tbb::blocked_range classes.
	Ray.h
	A Ray class.
	Reduce.h
	A unified wrapper for tbb::parallel_reduce and a naive std::future analog.
	SampleFromVoxels.h
	NearestNeighborSampler, TrilinearSampler, TriquadraticSampler and TricubicSampler.
	Stencils.h
	Defines various finite-difference stencils that allow for the computation of gradients of order 1 to 5, mean curvatures, gaussian curvatures, principal curvatures, tri-linear interpolation, zero-crossing, laplacian, and closest point transform.
