#878 new defect
broad q resolution for USANS and negative q for USANS

Description
The slit resolution function in sasmodels/resolution.py assumes that q_x>0 and that delta q_x << q_x. However, with wide open slits at low q it is possible that the resolution calculation should include theory values from q_x < 0.

Note: See

Part of the solution will be to change the extrapolation function which picks the q points for low q values as indicated in ticket #835 comments. The other part will be updating the slit_resolution function to handle negative q values correctly.
