FrictionSimulation class

A simulation that applies a drag to slow a particle down.

Models a particle affected by fluid drag, e.g. air resistance.

The simulation ends when the velocity of the particle drops to zero (within the current velocity tolerance).

FrictionSimulation(double drag, double position, double velocity, {Tolerance tolerance = Tolerance.defaultTolerance, double constantDeceleration = 0}): Creates a FrictionSimulation with the given arguments, namely: the fluid drag coefficient cₓ, a unitless value; the initial position x₀, in the same length units as used for x; and the initial velocity dx₀, in the same velocity units as used for dx.
FrictionSimulation.through(double startPosition, double endPosition, double startVelocity, double endVelocity): Creates a new friction simulation with its fluid drag coefficient (cₓ) set so as to ensure that the simulation starts and ends at the specified positions and velocities.

tolerance ↔ Tolerance: How close to the actual end of the simulation a value at a particular time must be before isDone considers the simulation to be "done".
