Leonardo de Moura	f786d21b0f	feat(library/system): basic support for random numbers ... @aqjune @nunoplopes: This commit adds basic support for random numbers. It defines a random number generator interface, and an basic implementation based on the Haskell one. We can add more implementations in the future if neeeded. The new test program has a few examples. BTW, this is a pure Lean implementation. If we need more performance we can provide an implementation using C++.	2018-02-15 14:36:28 -08:00
