Allow non-proportional hazards for some but not all covariates #6

Closed chjackson closed 10 months ago

This would be nice for "completion". Obvious syntax would be

survextrap(Surv(time,event) ~ agegroup + treatment, nonprop = ~ treatment, ...)

Though more experience and motivating examples are wanted for non-proportional hazards models in general.
