equals
Rounded, orientation-sensitive identity: equal when every component matches at the SCALE quantum.
Swapping the endpoints negates all six components and compares unequal; compare canonical on both sides for unoriented equivalence. At-infinity magnitudes compare as data. Identity is exact-class: a subclass instance and a plain Dipole never compare equal.
Return
true iff other shares this object's exact class and its six components all match after rounding.
Parameters
other
The object to compare against.
