initialising csrf protector with parameters for different behaviors

init function in csrfprotector class accepts parameters that allow developers to override default configurations (as those in files). csrfprotector::init looks like

public static function init($length = null, $action = null) {
    /* ... */
}

The parameter $length shall be used to set custom length for token_length for that page.
The parameter $action (array) shall be used to set custom action for failed validation for that page.

Example usage

include_once __DIR__ ."/libs/csrf/csrfprotector.php";
csrfprotector::init(25);

The above example, makes sure the length of csrf_token is 25 charecters

include_once __DIR__ ."/libs/csrf/csrfprotector.php";
csrfprotector::init(25, array(0,2));

The above example, makes sure the length of csrf_token is 25 charecters & default action taken is strip in case of failed validation for GET request & forbidden for POST request
