/**
 * A process factory is used to override default process (<code>IProcess</code>)
 * creation by the debug plug-in, and can be contributed via plug-in XML. When a
 * new process is created via <code>DebugPlugin.newProcess(..)</code>, the
 * launch configuration associated with the specified launch is consulted for
 * a process factory attribute (<code>DebugPlugin.ATTR_PROCESS_FACTORY_ID</code>). If
 * present, the associated process factory is consulted to create a process for
 * the launch. If not present a default process implementation is created and
 * returned by the debug plug-in.
 * <p>
 * Following is example plug-in XML that contributes a process factory.
 * <pre>
 * &lt;extension point="org.eclipse.debug.core.processFactories"&gt;
 *   &lt;processFactory
 *           id="com.example.ExampleIdentifier"
 *           class="com.example.ExampleProcessFactory"&gt;
 *   &lt;/processFactory&gt;
 * &lt;/extension&gt;
 * </pre>
 * The attributes are specified as follows:
 * <ul>
 * <li>id - a unique identifier for this extension point</li>
 * <li>class - the fully qualified name of a class the implements
 *   <code>IProcessFactory</code></li>
 * </ul>
 * </p>
 * <p>
 * Clients contributing a process factory are intended to implement this interface.
