// CONSTRUCTION: with (a) no initializer or (b) an integer

// that specifies the initial state of the generator

//

// ******************PUBLIC OPERATIONS*********************

// Return a random number according to some distribution:

// int randomInt( ) --> Uniform, 1 to 2^31-1

// int random0_1( ) --> Uniform, 0 to 1

// int randomInt( int low, int high ) --> Uniform low..high
