public class StudentPolarGen
This class implements Student random variate generators using the polar method of. The code is adapted from UNURAN.
The non-static nextDouble method generates two variates at a time and the second one is saved for the next call. A pair of variates is generated every second call. In the static case, two variates are generated per call but only the first one is returned and the second is discarded.
