/**
* Rule checking that uploaded file size does not exceed the given limit
*
* The Rule needs one configuration parameter for its work: the size limit.
* This limit can be passed either to
* {@link HTML_QuickForm2_Rule::__construct() the Rule constructor} as local
* configuration or to {@link HTML_QuickForm2_Factory::registerRule()} as
* global one. As usual, global configuration overrides local one.
*
* Note that if file upload failed due to upload_max_filesize php.ini setting
* or MAX_FILE_SIZE form field, then this rule won't even be called, due to
* File element's built-in validation setting the error message.
*
* The Rule considers missing file uploads (UPLOAD_ERR_NO_FILE) valid.
