\brief Distribute a brake response to the wheels of a vehicle.
\note The brake torque of each wheel on the ith wheel is brakeCommand * maxResponse * wheelResponseMultipliers[i].
\note A typical use case is to set maxResponse to be the vehicle's maximum achievable brake torque
that occurs when the brake command is equal to 1.0.  The array wheelResponseMultipliers[i] would then be used
to specify the maximum achievable brake torque per wheel as a fractional multiplier of the vehicle's maximum achievable brake torque.
