* @brief
* Class for an abstract formula tree with a R (reward) operator node over a reward interval as root.
*
* Has a reward path formula as sub formula/tree.
*
* @par Semantics
* The formula holds iff the reward of the reward path formula is inside the bounds
* specified in this operator
*
* 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)
*
* @tparam FormulaType The type of the subformula.
* The instantiation of FormulaType should be a subclass of AbstractFormula, as the functions
* "toString" and "conforms" of the subformulas are needed.
*
* @see AbstractFormula
* @see PathBoundOperator
