With logical coupling, if two entities are changed together many times, they get a shorter distance.
distance(e1, e2) = 1/c(e1, e2) if c(e1, e2) > 0 otherwise infinity. c(e1, e2) is the count of times e1 and e2 have been changed together.
I have not implemented the spatial entity in v0, as it is a bit tricky to identify the exact file that introduced a bug from a fix commit. For now, only the files modified in a bug-fix commit are put in the cache.
