returns the contained item with the highest value.
This function returns a pointer to the PolicyPoolItemInterface contained in this Policy pool with the highest (heuristic) value.
Heuristic is between brackets, because this function is typically used when we found lower bounds (i.e. full policies) and then select the maximum lowerbound.
Because this class always 'select's the best ranked policy, this function does the same as 'Select()'.
Implements PolicyPoolInterface.

initializes the policy pool with the empty joint policy and a heuristic value set to infinuty (i.e., DBL_MAX)
A pointer to a Interface_ProblemToPolicyDiscretePure is needed to create the joint policy.

Copy assignment operator.
This must be implemented by the derived class (with this prototype). For an example, see PolicyPoolJPolValPair.
For now, this function is purely abstract. Might there be some members added to this (base) class, then an implementation could be made. This should then be called using PolicyPoolInterface::operator=(o) from the copy assignment operator of the derived class. See also http://www.icu-project.org/docs/papers/cpp_report/the_assignment_operator_revisited.html.

Removes the item returned by 'Select'.
This removes the next PolicyPoolItem (a wrapper for a partial joint policy, together with some properties), as would be returned by 'Select'.

remove the GetBestRanked() item
Removes the PolicyPoolItemInterface contained in this Policy pool with the highest (heuristic) value. (as is returned by GetBestRanked() )
Because this class always 'select's the best ranked policy, this function does the same as 'Pop()'.

The 'Select' operator from refGMAA.
This returns a reference to the next PolicyPoolItem (a wrapper for a partial joint policy, together with some properties).
The returned PolicyPoolItem is not removed from the PolicyPool.
