\brief Compute the brake torque response to an array of brake commands.
\param[in] brakeCommands is the array of input brake commands to be applied to the vehicle.
\param[in] nbBrakeCommands is the number of input brake commands to be applied to the vehicle.
\param[in] longitudinalSpeed is the longitudinal speed of the vehicle.
\param[in] wheelId specifies the wheel that is to have its brake response computed.
\param[in] brakeResponseParams specifies the per wheel brake torque response to each brake command as a nonlinear function of brake command and longitudinal speed.
\param[out] brakeResponseState is the brake torque response to the input brake command. 
\note commands.brakes[i] and brakeResponseParams[i] are treated as pairs of brake command and brake command response.
