Previously, all the ApplyPolicy functions had the same name and used template resolution to figure out which one to use. This was pretty clear at first when there was just one for fields and one for cell sets. But then it grew to several different types, particularly for fields. It was hard to look at the code and figure out which form of ApplyPolicy was being used, and compilers were starting to get confused. Resolve the problem by giving all the methods unique names to make it clear which one you expect to be called.
