An ArrayHandle that provides a source of random bits.
ArrayHandleRandomUniformBits is a specialization of ArrayHandleImplicit. It takes a user supplied seed and hash it with the a given index value. The hashed value is the value of the array at that position.
Currently, Philox2x32x10 as described in the "Parallel Random Numbers: As Easy as 1, 2, 3," Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis (SC11) is used as the hash function.
Note: In contrast to traditional random number generator, ArrayHandleRandomUniformBits does not have "state", i.e. multiple calls the Get() method with the same index will always return the same hash value. To ge a new set of random bits, create a new ArrayHandleRandomUniformBits with a different seed.
