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/AbstractMarkersOperation.java
* 
	 * @return the array of markers that have been updated or created, or
	 *         <code>null</code> if no markers have been created or updated.
	 */
	public IMarker[] getMarkers() {
		return markers;
	}
	/**
	 * Return whether the markers known by this operation currently exist.
	 * 
	 * @return <code>true</code> if there are existing markers and
	 *         <code>false</code> if there are no known markers or any one of
	 *         them does not exist
	 */
	protected boolean markersExist() {
		if (markers == null || markers.length == 0) {
			return false;
		}
		for (int i = 0; i < markers.length; i++) {
			if (!markers[i].exists()) {
				return false;
			}
		}
		return true;
	}
	/**
	 * Return a status indicating the projected outcome of undoing the marker
	 * operation. The receiver is not responsible for remembering the result of
