bn::regular_bg_map_ptr class
#include <bn_regular_bg_map_ptr.h>

std::shared_ptr like smart pointer that retains shared ownership of a regular background map.

Several regular_bg_map_ptr objects may own the same regular background.

The regular background map is released when the last remaining regular_bg_map_ptr owning it is destroyed.
