eb483f2216949400bfef8f6deb5320f071445626Christian Maeder Provides data structures logic (co)morphisms.
eb483f2216949400bfef8f6deb5320f071445626Christian Maeder Logic (co)morphisms are just collections of
9929f81562adecc8aafaefb14a0159afcf4a3351Christian Maeder functions between (some of) the types of logics.
