About package
--------------
Mir-Random [1] is a random number generator library that covers C++ STL [2]. 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.

Release v0.2.5
--------------
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) [3] 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 B├╝rger (@krox). Multivariate normal RNG uses private Cholesky decomposition, which has not unittests yet. PRs are welcome.

My fork of lubeck has a branch where I was doing some work on adding cholesky that has some unittests if you want to borrow them (probably needs some adjustments).

It's what prompted eachLower/eachUpper. I was like, there's gotta be a pretty way of doing this and got completely distracted from cholesky!
