title: Optaplanner List Planning variable
body: <p>Downloaded OptaPlanner examples, testing them. In the Meeting Scheduling example provided, a single planning variable is returned in the solved solution. for example, for a meeting scheduling, one Room is returned. I am planning to allocate multiple rooms for a single meeting schedule if the locations are different (assuming VC enabled for remote rooms). Current Meeting Scheduling example does not show this. Do I need to change the planning variable room to a List?</p>
