#1083 closed defect (fixed)

Magnetic models not being computed

Description

This was broken out from ticket #1004 about default for magnetic sld. This is a blocker for 4.2.

From Previous ticket:
4.1.2 does not appear to compute magnetic models. Try for example, a sphere with:

sld: 4.50078  M0:0.317  mtheta:19.8  mphi:154.5
sld_solvent: 3.75713  M0:4.385  mtheta:-51.4  mphi:155.1
radius: 200

and compare with the equivalent from sascomp:

$ sascomp sphere -magnetic -nq=400 -pars -random=547121 radius=200

Sasview is identifying sphere models as non-oriented, and therefore calling the 1D model with q = sqrt(qx^2 + qy^2) rather than the 2D model with qx, qy.

In 05df1ded9ed7edca9420c90b0d39d936b8e1c97e/sasmodels:

fix magnetic modelling for spherosymmetric shapes. Fixes #1083.
