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/CreateFileOperation.java
if (fileHandle.getParent().exists()) {
			resourceDescription = new FileDescription(fileHandle, linkLocation,
					createFileContentDescription(fileHandle, contents));
		} else {
			
			
			ContainerDescription containerDescription = ContainerDescription
					.fromContainer(fileHandle.getParent());
			containerDescription.getFirstLeafFolder()
					.addMember(
							new FileDescription(fileHandle, linkLocation,
									createFileContentDescription(fileHandle,
											contents)));
			resourceDescription = containerDescription;
		}
		setResourceDescriptions(new ResourceDescription[] { resourceDescription });
	}
	/*
	 * Create a file state that represents the desired contents and attributes
	 * of the file to be created. Used to mimic file history when a resource is
	 * first created.
	 */
	private IFileContentDescription createFileContentDescription(
			final IFile file, final InputStream contents) {
		return new IFileContentDescription() {
			/*
			 * (non-Javadoc)
			 * 
			 * @see org.eclipse.ui.internal.ide.undo.IFileContentDescription#getContents()
