Functions
template<class InputIt , class OutputIt >
void	mfem::InclusiveScan (bool use_dev, InputIt d_in, OutputIt d_out, size_t num_items)
template<class InputIt , class OutputIt , class ScanOp >
void	mfem::InclusiveScan (bool use_dev, InputIt d_in, OutputIt d_out, size_t num_items, ScanOp scan_op)
	Performs an inclusive scan of [d_in, d_in+num_items) -> [d_out, d_out+num_items). This call is potentially asynchronous on the device.
template<class InputIt , class OutputIt , class T , class ScanOp >
void	mfem::ExclusiveScan (bool use_dev, InputIt d_in, OutputIt d_out, size_t num_items, T init_value, ScanOp scan_op)
template<class InputIt , class OutputIt , class T >
void	mfem::ExclusiveScan (bool use_dev, InputIt d_in, OutputIt d_out, size_t num_items, T init_value)
template<class InputIt , class FlagIt , class OutputIt , class NumSelectedIt >
void	mfem::CopyFlagged (bool use_dev, InputIt d_in, FlagIt d_flags, OutputIt d_out, NumSelectedIt d_num_selected_out, size_t num_items)
	Equivalent to *d_num_selected_out = std::copy_if(d_in, d_in+num_items, d_out, [=](auto iter){ return d_flags[iter-d_in]; }) - d_out;.
template<class InputIt , class OutputIt , class NumSelectedIt , class SelectOp >
void	mfem::CopyIf (bool use_dev, InputIt d_in, OutputIt d_out, NumSelectedIt d_num_selected_out, size_t num_items, SelectOp select_op)
	Equivalent to *d_num_selected_out = std::copy_if(d_in, d_in+num_items, d_out, select_op) - d_out;.
template<class InputIt , class OutputIt , class NumSelectedIt >
void	mfem::CopyUnique (bool use_dev, InputIt d_in, OutputIt d_out, NumSelectedIt d_num_selected_out, size_t num_items)
	equivalent to *d_num_selected_out = std::unique_copy(d_in, d_in+num_items, d_out) - d_out;
