/*!
* @brief
* Class for a Abstract formula tree with a R (reward) operator without declaration of reward values
* as root.
*
* Checking a formula with this operator as root returns the reward for the reward path formula for
* each state
*
* Has one Abstract path formula as sub formula/tree.
*
* @note
* This class is a hybrid of a state and path formula, and may only appear as the outermost operator.
* Hence, it is seen as neither a state nor a path formula, but is directly derived from AbstractFormula.
*
* @note
* This class does not contain a check() method like the other formula classes.
* The check method should only be called by the model checker to infer the correct check function for sub
* formulas. As this operator can only appear at the root, the method is not useful here.
* Use the checkRewardNoBoundOperator method from the DtmcPrctlModelChecker class instead.
*
* The subtree is seen as part of the object and deleted with it
* (this behavior can be prevented by setting them to NULL before deletion)
