/**
 * Compare the <b>path</b> of two files for order (see {@link File#getPath()}).
 * <p>
 * This comparator can be used to sort lists or arrays of files
 * by their path either in a case-sensitive, case-insensitive or
 * system dependent case sensitive way. A number of singleton instances
 * are provided for the various case sensitivity options (using {@link IOCase})
 * and the reverse of those options.
 * <p>
 * Example of a <i>case-sensitive</i> file path sort using the
 * {@link #PATH_COMPARATOR} singleton instance:
 * <pre>
 *       List&lt;File&gt; list = ...
 *       ((AbstractFileComparator) PathFileComparator.PATH_COMPARATOR).sort(list);
 * </pre>
 * <p>
 * Example of a <i>reverse case-insensitive</i> file path sort using the
 * {@link #PATH_INSENSITIVE_REVERSE} singleton instance:
 * <pre>
 *       File[] array = ...
 *       ((AbstractFileComparator) PathFileComparator.PATH_INSENSITIVE_REVERSE).sort(array);
 * </pre>
 * <p>
