Detailed Description

Updated MT19937 generator adapted to provide an array for initialization.

MT19937 uses 5489 as default initial seed. Use this generator when interoperating with C++11's mt19937 class.

You should reseed the generator after a fork() to avoid multiple generators with the same internal state.
