## NOTE: as of April 26, 2014, as part of first pass on fixing categories,
## all the appends to shape_list or shape_independent_list are
## commented out. They should be possible to remove. They are in
## fact a "category" of model whereas the other list are actually
## "attributes" of a model. In other words is it a structure factor
## that can be used against a form factor, is it a form factor that is
## knows how to be multiplied by a structure factor, does it have user
## defined number of parameters, etc.
##
## We hope this whole list will be superseded by the new C models
## structure where each model will provide a method to interrogate it
## about its "attributes" -- then this long list becomes a loop reading
## each model in the category list to populate the "attribute"lists.
## We should also refactor the whole category vs attribute list
## structure when doing this as now the attribute lists think they are
## also category lists.
