/*!
 * @brief
 * Class for an abstract formula tree with a P (probablistic) operator without declaration of probabilities
 * as root.
 *
 * Checking a formula with this operator as root returns the probabilities that the path formula holds
 * (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 checkProbabilisticNoBoundOperator 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)
 *
