Hi there!

Since I needed to use {array_set ...} noticed there are a couple of things to
fix.

In CGSimpleSmarty.module.php:

1. line 65 the function is registered as "cgsi_array_set", so the help
documentation example should be updated to use {cgsi_array_set ...}

2. line 91

$data = $smarty->get_template_var($name);

should be

$data = $smarty->get_template_vars($name);

Take care ;)
