/**
* Returns the next pseudo-random value from the generator. If the rotate parameter is true, then
* the random number is rotated such that the midpoint of the first bin will fall at zero. e.g. If
* there are eight bins, and the random number falls in the first bin, .0625 is subtracted from
* the number. A modulus of 1 is then applied so that values will remain in the interval zero to
* 1. This way, the values can be post-multiplied by tau=2*pi to get an angle.
