public interface TimeOfImpactDetector
Sometimes called Continuous Collision Detection, implementing classes are used to detect collisions
between Convex
Shape
s given their initial and final state of a time step. This information
can then be used to solve a collision that was missed during that period.
These algorithms are generally very computationally expensive.

Convex
Shape
s collide given their current positions and orientation
and the rate of change their position and orientation, returning the time of impact within an epsilon.
If a collision is detected, the toi
parameter will be filled with the time of impact and the
separation at the time of impact.
If a time of impact is detected, the time will be in the range [0, 1]. This can be used, along with the change and position and orientation, to place to the shapes at the time of impact. Note that the shapes will still be separated, by a small amount, at the time of impact.
This method returns false if the shape do not collide.

Shape
s collide given their current positions and orientation
and the rate of change their position and orientation in the time range of [t1, t2] and returning the time of
impact within an epsilon.
