A version of the Random Gate that avoids repeating numbers.
When generating a new number, it guarantees it will be different than the last 3 numbers it outputted.
Only outputs Integers. (there wouldn't be much point in avoiding duplicate decimal numbers)
If you want to clear its history, use the "Clear Exec"
If you want to change how many numbers ago it keeps track of, then copy more of the part of the circuit that is repeated 3 times, and change the "length of history" variable.
