heat_world bug?

[thomasrarris]

In the heat_world puzzle, at the end of the ReferenceExecute function, the instruction buffer[index] = res; is missing after res=std::min(1.0f, std::max(-1.0f, res));.

Thanks for that - I have to admit that for heat world I didn't actually look at the output in detail, which is pretty much going against everything I've claimed about testing.
