(New in v2.5.1)

The basic simulator design assumes a single source at a given position $(x,y)$. This is important for the roulette simulator which expands $\psi$ around the apparent position corresponding to $(x,y)$.

The SourceConstellation makes it possible to add multiple sources to one constellation. This should work fine with raytrace, but there is not yet support to manage this with a roulette simulation.

To use a SourceConstellation each constituent source is created as usual and added to the constellation at a given $(x,y)$ coordinate, using the addLens() method.
