   Public Member Functions
       _RandomNumber ()
           Default constructor. Seed with 0.
       _RandomNumber (uint32_t __seed, uint64_t _M_supremum=0x100000000ULL)
           Constructor.
       unsigned long __genrand_bits (int __bits)
           Generate a number of random bits, run-time parameter.
       uint32_t operator() ()
           Generate unsigned random 32-bit integer.
       uint32_t operator() (uint64_t local_supremum)
           Generate unsigned random 32-bit integer in the interval [0,local_supremum).

Detailed Description
