update input->post or input->get methods

Hi, in joomla framework, one of my favorite functions are jinput->get methods, this series of methods used for getting variables from post or get or ... , not just that , you can tell what kind of variable you want of how it must filter input,
here is documentation of that :

i wish in next version of CI, we have this functions also, think, you can define TYPE and DEFAULT value of expected input variable instead of checking null and then converting,
