* Initial test and benchmark for mapEntity.Step(). * Removed `&& !m.hasPath()` from mapEntity.atTarget * Direction is now updated when the path node changes mid-step and target is updated when path is set. * Test improvements. * Deleted old benchmark function and tidying. * d2math.Abs added. * Abs benchmark and optimisation. * Negate and Distance benchmark. * Length and SetLength benchmark. * Lerp and Dot benchmark. * Cross and Normalize benchmark. * Angle and SignedAngle benchmark. * Trivial change to Vector.Abs()
