Trac update at 2016/10/09 17:49:25: pkienzle commented:

This is implemented in sasmodels/models/_spherepy.py as def sesans(z, sld, sld_solvent, radius), and appears in sasmodels as model_info.sesans.

This needs to be made available through sasmodels/sasview_model.py to the calculator(s) in sasview/src/sas/sascalc/fit/BumpsFitting.py or sasview/src/sas/sascalc/fit/AbstractFitting.py, and in sasview/src/sas/sasgui/perspectives/fitting/model_thread.py.

Yet another reason to refactor the modeling interface: the logic to choose the analytic sesans function if it exists, otherwise choose sesans.transform(I(q)) should only be in one place.
