Autogenerated parts of the model

• magnetism on each of the sld parameters
• vector parameters
• tied parameters
• linearize for loop
• need an easy way to reparameterize an existing model
• can't currently reference other models from within one model
• autogenerate figures for docs from demo parameters (or maybe default)

Existing models

• fix problems with specific models (see tickets)
• clean up model code (e.g., use J1c, sinc, etc.)
• move from NR J1

Integration

• slowly evolve the sasview model api
• preserve parameter order using ordered dict, with removing sort in GUI
• redo interface to resolution within sasview GUI so that it doesn't recalc q every time
• show min max in gui

Parameter enhancements

• display ER and VR when available
• access to effective radius in constraints
• don't use automatic constraint to set effective radius in product model
• *enhancement* allow model to define the derived parameters (possibly polydisperse)
• allow parameters not part of existing models for use in constraints (e.g., by having a zero model with k parameters)

GUI aspects

• show components separately for product and sum models
• weighted sum of several models (mixture models) to avoid e.g., p1_p2_radius
• can we do mixture models "on the fly"

Fitting Enhancements

• integer parameters not fit properly
• deweighting SAXS fits
• downsampling SAXS data
• assign cost to structure in the residuals
• mask of middle part of data (e. g., spurions)
