8c8209c08c large refactoring to keep only a simpler, easier CDCL(T) interface 
- only one functor to instantiate
- explicit state that is carried around
- remove minismt stuff

8076c06047 [bugfix] Eliminate duplicates in input clauses 
When adding clauses that conatins duplicates, the checking
of some proof would fail because there would sometime be multiple
littrals to resolve over. This fixes that problem.

4f5bb640ca [WIP] All is setup, remains to have real theories 
Architecture is now all setup, but theories for the smt and mcsat
solvers are currently dummy ones that are not doing anything.

2613926ab1 First changes for better persistent proofs 
This commit ensures that clauses now contain
all necessary information to construct the proof
graph (without relying on propagation reasons).
