+ Description: Converts a group name to an id.
+              In general, instead of using this function, you should
+              create a Group object and get its name. This function
+              does not offer any real performance advantage.
+
+ Params:      $name - The name of a group.
+
+ Returns:     The numeric id of the group with that name,
+              or C<undef> if the group does not exist.
