Title: Noise

This pull request refactors the noise-generating functions in the simulation module. I have written down precisely how I define SNR for the purpose of this. The one thing that I am feeling unsure about is the definition of the Rician noise from two Gaussians. My idea there follows up on Bago's suggestion on the mailing list.
