/**
 * This api exception returns more information than the default one. The aim it let the api consumer know better what is exactly the error without having to parse the error message.
 * If you consume an api that doesn't return an error_code or the extra data you need, consider improving the api and contribute
 * @param string $message
 *   the human friendly error message
 * @param string $error_code
 *   a computer friendly error code. By convention, no space (but underscore allowed)
 *  ex: mandatory_missing, duplicate, invalid_format
 * @param array $data
 *   extra params to return. eg an extra array of ids. It is not mandatory, but can help the computer using the api. Keep in mind the api consumer isn't to be trusted. eg. the database password is NOT a good extra data
