Rand() is equal to rand(), but thread-safe on unix, by means of a static mutex.
It takes an optional RandomState* argument, in order to avoid using the mutex in performance-critical code.
The functions RandInt, WithProb, RandUniform, RandGauss, RandPoisson and RandPrune now take an optional RandomState* argument.
Created the RandGauss2 function, which allows to create two random gaussian numbers in one shot (optimization of RandGauss).
Optimization of vector and matrix random set methods.
