Rename RandomSource.triangle arguments

[Sleepy-Horse]

The code of the function is

default double triangle(double min, double max) {
        return min + max * (this.nextDouble() - this.nextDouble());
    }

It can return min - max or min + max. I believe the arguments should be named center and maxDeviation.

Ah, because nextDouble() returns a value from 0.0 to 1.0 in each call, the value of the multiplier to max can range from 1.0 (1.0 - 0.0) to -1.0 (0.0 - 1.0), or thereabouts when accounting for 1.0 being the exclusive range (rather than inclusive). Looks fine to me, then.
