/**
 * This interface is designed to provide a common protocol for Objects that wish to execute 
 * code while they are active. For example, Runnable is implemented by class Thread.  
 * Being active simply means that a thread has been started and has not yet been stopped. 
 * <p>
 * In addition, Runnable provides the means for a class to be active while 
 * not subclassing Thread. A class that implements Runnable can run without
 * subclassing Thread by instantiating a Thread instance and passing itself in
 * as the target.  In most cases, the Runnable interface should be used if you are only planning 
 * to override the run() method and no other Thread methods.  
 * This is important because classes should not be subclassed
 * unless the programmer intends on modifying or enhancing the fundamental
 * behavior of the class.
