This is a bit great tool.
but uses 3 CEs
(ONLY for that project).1 ce destructor, 1 ce emeralds color machine changer, and 3rd ce is SORTER.
Rockford also needs to have sorted it's emeralds

In future i do the BD diamonds section (not near future...)
But in NEAR future i do the CE-keys to sorting
in other place of course (upper sender will be emeralds color machine changer)But the CE size can grow then to 8 CEs!
