* Sort out "const" in prototypes, it looks odd since there are constsfor many functions which modify the state.  (Applies to both qrng and rng)*  It would be useful to include functions to generate quasi-random  number distributions (at least the Gaussian distribution)? obviously  the Box-Mueller algorithm cannot be used to maintain the low  discrepancy characteristics of the sequence, there are several  methods suggested in the literature but it isn't at all my field so  I'm not sure which is to be preferred.
