API

uniqueRandomAtDepth(min, max, [depth])

Returns a function that when called will return a random number that's never the same as the previous. If depth is provided it will ensure that the random is unique relative to the last n results. So if you pass in 5 it will ensure that the return value is unique relative to the last 5 results.
