+Validating An Array (Other Than The $_POST Array)
+=================================================
+
+Sometimes you may want to validate an array that does not originate from $_POST data.
+
+In this case, you can specify the array to be validated::

+      $data = array(

+		  'passconf' => 'mypassword'

+Creating validation rules, running the validation and retrieving error messages works the same whether you are
+validating $_POST data or an array.

+Tokens may be either regenerated on every submission (default) or kept the same throughout the life of the CSRF cookie. The default regeneration of tokens provides stricter security but may result in usability concerns as other tokens become invalid (back/forward navigation, multiple tabs/windows, asynchronous actions, etc).
