Detailed Description

This is the base class for random number generators based
        on specific distributions. This Pseudorandom Number Generator
        is based on the MRG32k3a set by L'Eucyer. See attached paper
        "An Object-Oriented Random-Number Package with many Long
        Streams and Substreams" by L'Ecuyer, Simard, Chen, and Kelton

    Form name: LcRand
    Slots:
         Seed:               the seed to start the random number generator
         Antithetic:         boolean (true is x>0) for antithetic operation (return 1-U instead of U)
         IncreasedPrecision: boolean (true is x>0) for using increased precision (53bit double)

    Output: (0 <= x <= 1) as a double via getNextRand(); method
