* Default tcf launch configuration delegate implementation.
* <p>
* The launch configuration delegate implements the bridge between the native Eclipse launch
* configuration framework and the stepper engine. The delegate is standard for all
* launch configurations which supports extensible and modularized launching.
* <p>
* <b>Implementation Details</b>:<br>
* <ul>
* <li>The launch configuration delegate signals the completion of the launch sequence via
* the custom {@link ILaunch} attribute {@link ICommonLaunchAttributes#ILAUNCH_ATTRIBUTE_LAUNCH_SEQUENCE_COMPLETED}.</li>
* <li>The launch configuration delegates enforces the removal of the launch from the Eclipse
* debug platforms launch manager if the progress monitor is set to canceled or an status with
* severity {@link IStatus#CANCEL} had been thrown by the stepper implementation.</li>
* <li>The launch configuration delegate creates launches of type {@link Launch}.</li>
* </ul>
