    Class EllipticalTrajectory

    Axis-aligned ellipse in the XY plane, swept at a constant parameter rate (not constant arc speed).

    θ(t) = phase + angularVelocity · t
p(t) = center + (rx·cos θ, ry·sin θ, 0)
v(t) = ω · (−rx·sin θ, ry·cos θ, 0)
a(t) = −ω² · (rx·cos θ, ry·sin θ, 0)

    duration is one revolution of the parameter, 2π / |ω|.
