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