RandomGenerator:getSeed
Gets the seed of the random number generator object.

The seed is split into two numbers due to Lua's use of doubles for all number values - doubles can't accurately represent integer values above 2^53, but the seed value is an integer number in the range of 2^64 - 1.
low, high = RandomGenerator:getSeed()
low number Integer number representing the lower 32 bits of the RandomGenerator's 64 bit seed value.
high number Integer number representing the higher 32 bits of the RandomGenerator's 64 bit seed value.
