analytical models for sesans (Trac #342)

[pkienzle]

Include the analytical and published models for SESANS into sasview. For example the solid sphere, the cylinder, the ellipsoids, perfect inhomogenous solid, multi-shell spheres.

While not part of the core task of "integrating SESANS into GUI" which can use all the SANS models already built this is critical to start as it directly impacts the GUI (and infrastructure) designs. How to label a model as being in correlation space instead of Fourier space? How to structure so GUI can figure out which models to present to user (e.g. the normal sphere or the SESANS sphere)... and should we, for sake of clean architecture "make all models the same" so that a transform can be applied to Fourier models, but also to the correlation space models to compare to data in Fourier space?

Am thus making this making this not only a 4.0 ticket but labeling it "critical"

• butler changed priority from "minor" to "critical"

Now that we have an alpha2 out this ongoing work needs to move to +1

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

This is certainly useful. We can look together which analytical models are available. It aren’t many, but most of them are relevant in practice. Here I can contribute in describing the models. I cannot do anything any longer with the coding.
