For two angles a and b, between(a, b)
returns the smaller of a.getAngleTo(b)
and b.getAngleTo(a)
.
The result will be in the range [0, π].
If one interprets an angle in [0, 2π) as a point on the unit circle, then between
can be thought of as computing the arc length of the shortest unit circle segment between the points for a and b.

For two normalized angles a and b, center(a, b)
returns the angle m such that a.getAngleTo(m)
is equal to m.getAngleTo(b)
