/**
 * TVar_dumper class.
 * original source: https://code.google.com/p/prado3/source/browse/trunk/framework/Util/TVar_dumper.php
 *
 * TVar_dumper 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.
 *
 * TVar_dumper can be used as follows,
 * <code>
 *   echo TVar_dumper::dump($var);
 * </code>
