Bug 173902 remove EXPERIMENTAL markings from 3.3 IDE Undo API
Need to remove the EXPERIMENTAL javadoc from the new API I introduced in 3.3. See org.eclipse.ui.ide.undo org.eclipse.jface.fieldassist
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/ide/undo/AbstractWorkspaceOperation.java
*            the progress monitor to be used for computing the status
	 * @return the status indicating the projected outcome of executing the
	 *         receiver
	 * 
	 * @see org.eclipse.core.commands.operations.IAdvancedUndoableOperation#computeUndoableStatus(org.eclipse.core.runtime.IProgressMonitor)
	 * @see #setQuietCompute(boolean)
	 */
	public IStatus computeExecutionStatus(IProgressMonitor monitor) {
		IStatus status = Status.OK_STATUS;
		
		if (quietCompute) {
			return status;
		}
		IResourceChangeDescriptionFactory factory = ResourceChangeValidator
				.getValidator().createDeltaFactory();
		if (updateResourceChangeDescriptionFactory(factory, EXECUTE)) {
			boolean proceed = IDE
					.promptToConfirm(
							getShell(null),
							UndoMessages.AbstractWorkspaceOperation_SideEffectsWarningTitle,
							NLS
									.bind(
											UndoMessages.AbstractWorkspaceOperation_ExecuteSideEffectsWarningMessage,
											getLabel()), factory.getDelta(),
							modelProviderIds, true );
			if (!proceed) {
				status = Status.CANCEL_STATUS;
			}
		}
		return status;
