Compact Functions
template<bool isBackward>
__global__ void	computeNumValidElements (size_t *d_numValidElements, const unsigned int *d_indices, const unsigned int *d_isValid, size_t numElements)
	Compute the number of valid flags in an array given the array and its exclusive sum scan.
template<class T , bool isBackward>
__global__ void	compactData (T *d_out, size_t *d_numValidElements, const unsigned int *d_indices, const unsigned int *d_isValid, const T *d_in, unsigned int numElements)
	Consolidate non-null elements - for each non-null element in d_in write it to d_out, in the position specified by d_isValid. Called by compactArray().
