| ClausesGraph | 
 This class describes the relation between different clauses in a CNF. 
 | 
| ClausesSmallerThanFeature | 
 Ordering used to sort the clauses in a quantified formula. 
 | 
| Constraint.Top | Deprecated | 
| ConstraintAwareSyntacticalReplaceVisitor | 
 In KeY 1.x we supported a free variable calculus based on meta variables.

| EqualityConstraint | Deprecated | 
| EqualityConstraint.ECPair | |
| ExistentiallyConnectedFormulasFeature | 
 Binary feature that return zero if two given projection term is CS-Releated. 
 | 
| HandleArith | 
 This class is used to prove some simple arithmetic problem which are 
 a==b, a>=b, a<=b; Besides it can be used to prove that a>=b or a<=b by 
 knowing that c>=d or c<=d;

| InstantiationCost | 
 Feature that returns the number of branches after instantiated the quantifier
 formula.

| RecAndExistentiallyConnectedClausesFeature | 
 Binary Term Feature return zero if root is a CNF quantifier formula with several 
 clauses.

| Substitution | 
 This class decribes a substitution,which store a map(varMap) from quantifiable 
 variable to a term(instance). 
 | 
| TriggersSet | 
 This class is used to select and store  
Triggers 
 for a quantified formula in Prenex CNF(PCNF). | 
| TriggerUtils | |
| TwoSidedMatching | 
 Matching triggers within another quantifier expression.
