/**
 * CVarDumper is intended to replace the buggy PHP function var_dump and print_r.
 * It can correctly identify the recursively referenced objects in a complex
 * object structure. It also has a recursive depth control to avoid indefinite
 * recursive display of some peculiar variables.
 *
 * CVarDumper can be used as follows,
 * <pre>
 * CVarDumper::dump($var);
 * </pre>
