> As identified in MATH-1154, initialization of the WellXXX rngs is quite
> costly as some internal arrays have to be computed.
> Most of these initializations are specific to the type of rng, e.g.
> Well19937a and will not change afterwards, thus could be initialized in a
> static way.
> Due to implementation details, i.e. the relevant fields are declared
> protected in the base class AbstractWell, such a change would not be
> backwards compatible and will have to be postponed to 4.0
