3.11 A wormhole example

Here is an example of a simulation that contains both an SDF portion and a DE portion. In this example, a Poisson process where particles have value 0.0 is sent into an SDF wormhole, where Gaussian noise is added to the samples. This demo shows how easy it is to use the SDF stars to perform computation on DE particles. The overall delay of the SDF wormhole is zero, so the result is simply Poisson arrivals of Gaussian noise samples.

A Wormhole has an outer domain and an inner domain. The outer domain is determined by the current domain at the time the user starts the defgalaxy command to create the wormhole. The inner domain is determined by the domain command that appears inside the galaxy definition.
