Description

An "adaptor" class will be provided for users who'd like to test the new RNG implementations (MATH-1335) before upgrading their codes to the new API.

This class will implement the old RandomGenerator interface (but will delegate all the calls to the new classes); hence the only step required in order to use the new RNGs in existing code will be the replacement of the instantiations of the old RNG classes with instantiations of the adaptor.
For example,

RandomGenerator rng = new Well19937c(9876);

could be replaced with

RandomGenerator rng = new RngAdaptor(RandomSource.WELL_19937_C, 9876);

and subsequent usage of rng would be functionally identical.
