TEXT_NORTH	North direction as a string "[1]"
TEXT_SOUTH	South direction as a string "[2]"
TEXT_EAST	East direction as a string "[4]"
TEXT_WEST	West direction as a string "[8]"
ISDIAGONALDIR	True if the dir is diagonal, false otherwise
ISCARDINALDIR	True if direction is cardinal and false if not
NSCOMPONENT	True if the dir is north or south, false therwise
EWCOMPONENT	True if the dir is east/west, false otherwise
REVERSE_DIR	Inverse direction, taking into account UP\|DOWN if necessary.
NSDIRFLIP	Flips the dir for north/south directions
EWDIRFLIP	Flips the dir for east/west directions
MAPPING_DIRECTIONAL_HELPERS	Create directional subtypes for a path to simplify mapping.
