template<typename InputIterator1 , typename InputIterator2 , typename OutputIterator >
void	bolt::cl::gather (::bolt::cl::control &ctl, InputIterator1 map_first, InputIterator1 map_last, InputIterator2 input_first, OutputIterator result, const std::string &user_code="")
	This version of gather copies elements from a source array to a destination range according to a specified map. For each i in InputIterator1 in the range [map_first, map_last), gather copies the corresponding input_first[ map [ i ] ] to result[ i - map_first ].

void	bolt::cl::gather_if (bolt::cl::control &ctl, InputIterator1 map_first, InputIterator1 map_last, InputIterator2 stencil, InputIterator3 input_first, OutputIterator result, const std::string &user_code="")
	This version of gather_if copies elements from a source array to a destination range according to a specified map. For each i in InputIterator1 in the range [map_first, map_last), gather_if copies the corresponding input_first[ map [ i ] ] to result[ i - map_first ] if stencil[ i - map_first ] is true.

void	bolt::cl::gather_if (bolt::cl::control &ctl, InputIterator1 map_first, InputIterator1 map_last, InputIterator2 stencil, InputIterator3 input, OutputIterator result, Predicate pred, const std::string &user_code="")
	This version of gather_if copies elements from a source array to a destination range according to a specified map. For each i in InputIterator1 in the range [map_first, map_last), gather_if copies the corresponding input_first[ map [ i ] ] to result[ i - map_first ] if pred (stencil[ i - map_first ]) is true.
