The settings to accompany the apop_cross model, representing the cross product of two models (or, via recursion, a list of models of arbitrary length).
|apop_model * apop_cross_settings::model1|
The first model in the stack.
|apop_model * apop_cross_settings::model2|
The second model.
|char * apop_cross_settings::splitpage|
The name of the page at which to split the data. If
NULL, I send the entire data set to both models as needed.
