StdGen.genRange seems to have wrong value

SwiftCheck/Sources/SwiftCheck/Random.swift

Lines 84 to 86 in 9e53d13

	public var genRange : (Int, Int) {
	return (Int.min, Int.max)
	}

I wonder if it should be (1, 2147483562) or something like that (sorry, I have hard time figuring the exact numbers out). I mean, even though the type of the value produced by next is Int, the actual value is defined by the algorithm that operates in subdomain of 32-bit numbers.

Honestly, genRange is an artifact of the old non-deterministic RNG. It should be deprecated and removed in the next point release.
