* The array “ddTools::$tables” with its elements is declared directly in the class to make it clear.
* The field “alias_visible” will be added to ddTools::$documentFields only if the version of MODX is later than 1.0.11 for backward compatibility.
* The method “ddTools::unfoldArray” has been added. Converts a multidimensional array into an one-dimensional one joining the keys with '.' (see the description & examples).
