Modifier is used to uppercase a variable or string. Has short alias `up`.

This is equivalent to the PHP [strtoupper()](http://docs.php.net/strtoupper) function.
```smarty
{var $name = "Bzick"}
2014-01-29 12:01:31 +04:00
{$name} outputs Bzick
{$name|upper} outputs BZICK
{$name|up} outputs BZICK too
