====== Brake ======
The **Brake** function commands the NXT brick to Brake one or more of it's motors.
The **motors** parameter can be a single motor, for example just **"A"** or a combination of motors such as **"ABC"**.
Unlike the Stop function, this function actively brakes the motors using power from the battery.
nxt.Brake( motors );
====Example - Brake motors B and C====
nxt.Brake( "BC" );
