/* Marshal is class for serialize object data.
* This is just wrapper of serialize/unserialize,

*
* EXAMPLES
*
*    # dump data and save it to file.
*    $name = "hina chan";
*    $age = 15;
*    Marshal::save("dumped_file", array("Name" => $name, "Age" => $age));
*
*    # load data from file.
*    $data = Marshal::load("dumped_file");
