Mir-Random  is a random number generator library that covers
C++ STL . It is compatible with mir.ndslice, std.algorithm,
and std.range. In the same time mir.random has its own API, which
is more secure and safe compared with std.random.
Mir-Random got three major additions:
- System level `genRandomNonBlocking` and `genRandomBlocking` was
added to `mir.random.engine` by Sebastian Wilzbach (@wilzbach).
`unpredictableSeed` became more secure.
- Permuted Congruential Generator (PCG)  was added by Nicholas
Wilson (@thewilsonator) After a while it will replace Mersenne
Twister for default engine (`Random` alias).
- `SphereVariable`, `SimplexVariable`, `DirichletVariable`, and
`MultivariateNormalVariable` was added to `mir.random.ndvariable`
by Simon Bürger (@krox). Multivariate normal RNG uses private
Cholesky decomposition, which has not unittests yet. PRs are
