Detailed Description
A generator for unique ids.
The unique ids are 64-bit random unsigned random integers. The class is implemented as a singleton. The random generator is initialized upon startup using the current system time and date. Collisions are not excluded by design, but extremely unlikely. (To estimate the probability of collisions, note that 
, so it is unlikely you will see one in your lifetime.)
