Krang::UUID - provide unqiue identfiers
use Krang::ClassLoader 'UUID';
# create a new UUID string
$uuid = pkg('UUID')->new();
This is a wrapper around Data::UUID which provides a consistent
interface for all Krang classes. UUIDs returned are always in string
format (ex. 98DBE9EE-684A-11DB-8805-80D0EC6873C7) and thus may be
reliably compared with eq.
Returns a new UUID string.
