/**
 * @assertion Future<String> resolveSymbolicLinks()
 * Resolves the path of a file system object relative to the current working
 * directory, resolving all symbolic links on the path and resolving
 * all .. and . path segments.
 *
 * resolveSymbolicLinks uses the operating system's native file system API to
 * resolve the path, using the realpath function on linux and OS X, and the
 * GetFinalPathNameByHandle function on Windows. If the path does not point to
 * an existing file system object, resolveSymbolicLinks throws a
 * FileSystemException.
 *
 * On Windows the .. segments are resolved before resolving the symbolic link,
 * and on other platforms the symbolic links are resolved to their target before
 * applying a .. that follows.
 * @description Check that a FileSystemException is thrown if the path does not
 * point to an existing file system object.
