Organizing the PR a bit: we hook up the subtheories to TheoryFf we expose FF-related things via the C++/Pytohn API and SMT-LIB2 interface. we add a bunch of tests against these interfaces.

# A simple start-up/tear-down test for cvc5.

|
|
# This simple test just makes sure that the public interface is
|
|
# minimally functional. It is useful as a template to use for other
