/**
* The Runnable interface should be implemented by any
* class whose instances are intended to be executed by a thread. The
* class must define a method of no arguments called run.
*
* 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.
*
* 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.
