// C# code for testing the members of the Random class
// specified in the abbreviated UML diagram for Random.
// Usage: r.Next( ) returns a pseudo-random number
//        between 0 inclusive and 2^31 exclusive.
// r.Next(max) returns a number between 0 inclusive 
//        and max exclusive.
// r.Next(min, max) returns a number between min
//        inclusive and max exclusive.
// r.NextDouble( ) returns a number between 0.0 
//          inclusive to 1.0 exclusive.
