INDICATOR_
Indicator animation mode used to translate the selected tab indicator by growing and then shrinking the indicator, making the indicator look like it is stretching while translating between destinations.
The left and right side of the selection indicator translate out of step - with the right decelerating and the left accelerating (when moving right). This difference in velocity between the sides of the indicator, over the duration of the animation, make the indicator look like it grows and then shrinks back down to fit it's new destination's width.
