+ @example **Usage:**
+ seeded_rand(MAX, SEED).
+ MAX must be a positive integer; SEED is any string.
+
+ Generates a random whole number greater than or equal to 0 and less
+ than MAX, using the value of SEED for repeatable randomness. If SEED
+ starts with "$fqdn:", this is behaves the same as `fqdn_rand`.
