GenderInfo provides a method to determine the gender of a list/array
of objects when one knows the gender of each item of the list.
It does this in a locale sensitive manner.
The constructor initializes the object based on the locale data from
the current goog.labs.i18n.ListFormatSymbols.

ListFormat provides a method to format a list/array of objects to a string,
in a user friendly way and in a locale sensitive manner.
If the objects are not strings, toString is called to convert them.
The constructor initializes the object based on the locale data from
the current goog.labs.i18n.ListFormatSymbols.
