nuclear@0: /** DataSet is a generic resource database with fast O(logn) lookups by name
nuclear@0:  * it can be used for texture managers, mesh managers, sound effect managers etc
nuclear@0:  *
nuclear@0:  * The constructor takes a load function and a destructor function to be called
nuclear@0:  * when a nonexistent resource is requested and needs to be loaded, and when
nuclear@0:  * the DataSet is destroyed. The destructor is optional and can be set to null
nuclear@0:  * if not needed.
nuclear@0:  *
nuclear@0:  * Requesting a resource works by simply calling get, example:
nuclear@0:  * ----------------------------------------------------------
nuclear@0:  * \code
nuclear@0:  * Texture *load_texture(const char *fname);
nuclear@0:  * void free_texture(Texture *tex);
nuclear@0:  *
nuclear@0:  * DataSet<Texture*> texman(load_texture, free_texture);
nuclear@0:  * Texture *foo = texman.get("foo.png");
nuclear@0:  * \endcode
