Do not have bandwidth to deal with for 4.0 which is already mega late -- can do at code camp or beyond. Leaving a high priority but moving to +1

• butler changed milestone from "SasView 4.0.0" to "SasView Next Release +1"

sasmodels/product.py implements the product model as defined in !SasView when a form factor is multiplied by a structure factor. This could be used directly from sasview.

Rather than using ProductKernel, we could somehow make ER and VR into derived parameters that can be used in constraint expressions, and use constrained fitting to on a mixture model (sasmodels/mixture.py), with product rather than sum used to mix the models. This will be considerably more work, and belongs in a separate ticket.
