This function merges aidPERSONIDPAPERS with aidRESULTS.
Use it after tortoise.
This function is static: if aid* tables are changed while it's running,
probably everything will crash and a black hole will open, eating all your data.
NOTE: this is more elegant that merge_static but much slower. Will have to be improved
before it can replace it.
