Misleading comments DataGenerator

[lucaslaurent04]

Wrong types in phpdoc:

• $field_descriptor is an array
• $lang is string|null

equal/lib/equal/data/DataGenerator.class.php

Lines 15 to 17 in 325f177

	* @param string $field Field name.
	* @param string $field_descriptor Field descriptor.
	* @param string $lang Lang code of the language in which the value must be generated (for multilang fields).

The comment on $field_descriptor does not add any information and mislead on the type, why was it added ?
