Detailed Description

A random number generator, uniform in the range 0-1.

This class is a simple wrapper around C++11 Mersenne Twister engine.

The generator is always initialized with a seed equal to the current time. You can reset the seed by explicitly calling Rand::init(seed).

Default generator is std::mt19937.
