class PropertyAnimator :id=PropertyAnimator

This is a utility mixin class to make some Lume element properties animatable when provided a function. This allows animation of some properties like so:

const box = document.querySelector('lume-box')
box.rotation = (x, y, z, t, dt) => [x, ++y, z]
box.opacity = (opacity, t, dt) => opacity - 0.01

Currently it is only for any XYZValues properties (for example position, rotation, etc), or opacity.

For an XYZValues property, the function accepts the current x, y, z, time, and deltaTime values for the current frame, and should return the new desired values.

For opacity it is similar, but the function accepts a opacity, time, and deltaTime, and should return the new desired opacity.
