Data Structures
struct	distance_generator_struct

Typedefs
typedef struct distance_generator_struct *	distance_generator

Functions
distance_generator	new_distance_generator (int n_samples, int n_distances)
void	del_distance_generator (distance_generator d)
double	distance_generator_get_at_distance (distance_generator d, int i, int j, int which_distance)
double	distance_generator_get (distance_generator d, int i, int j)
void	distance_generator_set_function_data (distance_generator d, void(*lowlevel_dist_funct)(void *, int, int, double *), void *extra_data)
	defines distance calculation function wrapper, and all extra data needed by wrapper; no check is done here, but wrapper should return at least as many distances sd n_distances (wrapper functions can check)
void	distance_generator_set_which_distance (distance_generator d, int which_distance)
	distance wrapper may return several distances, but only one is returned by get(); this sets which one (should be called before e.g. clustering)
void	distance_generator_reset (distance_generator d)
