Title: Parabola intuition3 time line fix

Updated the parabola intuition 3 exercise to use a custom answer type so that it works with the time line view.

Added a new setCoord function for the movableLine. Previously it only had a moveTo animation call. An animation is not what is needed for the time line initialization.
