  Abstract:
  
      Simplify goal using subsumption based on unit propagation.

  Notes:
  
      Background: PDR generates several clauses that subsume each-other.
      Simplify a goal assuming it is a conjunction of clauses.
      Subsumed clauses are simplified by using unit-propagation 
      It uses the smt_context for the solver.
