/**
 * @assertion Future<bool> identical(
 *  String path1,
 *  String path2
 *  )
 * Checks whether two paths refer to the same object in the file system. Returns
 * a Future<bool> that completes with the result.
 *
 * Comparing a link to its target returns false, as does comparing two links
 * that point to the same target. To check the target of a link, use Link.target
 * explicitly to fetch it. Directory links appearing inside a path are followed,
 * though, to find the file system object.
 *
 * Completes the returned Future with an error if one of the paths points to an
 * object that does not exist.
 * @description Checks that this method completes with true if two paths refer
 * to the same object in the file system. Test absolute and relative path for
 * links
