/**
 * Javascript Form Validation Class
 *
 * This validation class works along with jQuery and CI's validation class
 * to provide a 0-time javascript implementation of the php validation. Use
 * is very easy. Just need to follow theese two steps:
 *
 * 1. Add the onsubmit method to the form:
 *
 * 		onsubmit="return validateForm()"
 *
 * 2. Add the following code at the end of page:
 *
 * 		< ?php echo $this->validation->getJsValidation(); ?>
