 * @brief
 * Abstract base class for Abstract path formulas.
 *
 * @attention This class is abstract.
 * @note Formula classes do not have copy constructors. The parameters of the constructors are usually the subtrees, so
 * 	   the syntax conflicts with copy constructors for unary operators. To produce an identical object, use the method
 * 	   clone().
 *
 * @note
 * 		This class is intentionally not derived from AbstractCslFormula, as a path formula is not a complete CSL formula.
