/**
 * This is the abstract form validator, which must be inherited by any custom
 * form validator in order to work properly.
 *
 * Please note that a default form validator already exists if you need a form
 * which does not require any particular action: `DefaultFormValidator`.
 *
 * A form validator should be called to validate any form instance (which is a
 * child of `AbstractForm`). Usually, this is used in controller actions to
 * validate a form sent by the user. Example:
 *
 * /**
 *  * Action called when the Example form is submitted.
 *  *
 *  * @param $exForm
 *  * @validate $exForm Romm.Formz:Form\DefaultFormValidator
 *  * /
 *  public function submitFormAction(ExampleForm $exForm) { ... }
 *
 *******************************************************************************
 *
 * You may use you own custom form validator in order to be able to use the
 * following features:
 *
 * - Pre-validation custom process:
 *   By extending the method `beforeValidationProcess()`, you are able to handle
 *   anything you want just before the form validation begins to loop on every
 *   field. This can be used for instance to (de)activate the validation of
 *   certain fields under very specific circumstances.
 *
 * - In real time custom process:
 *   After each field went trough a validation process, a magic method is called
 *   to allow very low level custom process. The magic method name looks like:
 *   "{lowerCamelCaseFieldName}Validated". For instance, when the "email" field
 *   just went trough the validation process, the method `emailValidated()` is
 *   called.
 *
 * - Post-validation custom process:
 *   After the validation was done on every field of the form, this method is
 *   called to allow you high level process. For instance, let's assume your
 *   form is used to calculate a price estimation depending on information
 *   submitted in the form; when the form went trough the validation process and
 *   got no error, you can run the price estimation, and if any error occurs you
 *   are still able to add an error to `$this->result` (in a controller you do
 *   not have access to it anymore).
