Radix Sort Functions
typedef unsigned int	uint
template<bool doFlip>
__device__ uint	floatFlip (uint f)
	Flips bits of single-precision floating-point number (parameterized by doFlip)
template<bool doFlip>
__device__ uint	floatUnflip (uint f)
	Reverses bit-flip of single-precision floating-point number (parameterized by doFlip)
template<class T , int maxlevel>
__device__ T	scanwarp (T val, volatile T *sData)
	Scans one warp quickly, optimized for 32-element warps, using shared memory.
__device__ uint4	scan4 (uint4 idata)
	Scans 4*CTA_SIZE unsigned ints in a block.
template<int ctasize>
__device__ uint4	rank4 (uint4 preds)
	Computes output position for each thread given predicate; trues come first then falses.
template<uint nbits, uint startbit>
__device__ void	radixSortBlock (uint4 &key, uint4 &value)
	Sorts one block.
template<uint nbits, uint startbit>
__device__ void	radixSortBlockKeysOnly (uint4 &key)
	Sorts one block. Key-only version.
