/**
 * Compare the <b>last modified date/time</b> of two files for order
 * (see {@link FileUtils#lastModifiedUnchecked(File)}).
 * <p>
 * This comparator can be used to sort lists or arrays of files
 * by their last modified date/time.
 * <p>
 * Example of sorting a list of files using the
 * {@link #LASTMODIFIED_COMPARATOR} singleton instance:
 * <pre>
 *       List&lt;File&gt; list = ...
 *       ((AbstractFileComparator) LastModifiedFileComparator.LASTMODIFIED_COMPARATOR).sort(list);
 * </pre>
 * <p>
 * Example of doing a <i>reverse</i> sort of an array of files using the
 * {@link #LASTMODIFIED_REVERSE} singleton instance:
 * <pre>
 *       File[] array = ...
 *       ((AbstractFileComparator) LastModifiedFileComparator.LASTMODIFIED_REVERSE).sort(array);
 * </pre>
