Detailed Description

Marsaglia's random number generator (same as UKQCD).

You should not instantiate this class because:

• there is a global object mdp_random
• each field "lattice" has a parallel generator "lattice.random(x)" Example:

         // print a uniform number in (0,1)
         cout << mdp_random.plain() << endl;
         // print a gaussian number
         cout << mdp_random.gaussian() << endl;
         // print a random SU(10) matrix
         cout << mdp_random.SU(10) << endl;
