Easing module

Make a cubic bezier interpolation function.

Linear interpolation function. Linear animations move at a constant speed.

Ease interpolation function. Ease animations start slowly, speed up, then end slowly. The speed of the animation is slightly slower at the end than the start.

Ease-in interpolation function. EaseIn animations start slow, then speed up towards the end.

Ease-out interpolation function. EaseOut animations start fast, then slow down towards the end.

Ease-in-out interpolation function. EaseInOut animations are similar to Ease but the start and end animation speed is symmetric.
