/// relationships are useful for solvers that generate some physical
/// entity as part of the solve process. An example of this would be
/// the fluid solver which may use another DOP object as a fluid source
/// to generate new fluid. Another example is the HDK sample Snow
/// solver or Hair solver which generate snow and hair using a source
/// object.
