The existing logic to loop over formatters is very pre-C++11, using void* batons, and function pointers, and raw memory allocations instead of safer more modern constructs

This is a first pass at a cleanup of that code, modernizing the "type X clear" commands, and providing the basic infrastructure I plan to use all over
More cleanup will come over the next few days
