Random Sampling (cupy.random)

CuPy's random number generation routines are based on cuRAND. They cover a small fraction of numpy.random.

The big difference of cupy.random from numpy.random is that cupy.random supports dtype option for most functions. This option enables us to generate float32 values directly without any space overhead.
