right now cdf to cgp has no sense of complete_obsv = TRUE - it's just naive averages for kids under a filter of studentids.
it needs to 'walk' the grade level seasons, and call mapviz_cgp multiple times (mapviz cgp now has a use_complete_obsv parameter) with complete_obsv true; this allows accurate matching of kids present in both ends of the growth window (preventing attrition from influencing things)
