Add Intent class and its extended classes
- Intent class is an abstract class for the intents
- ShortestPathIntent class extends Intent class that expresses shortest hop between source-destination pair
- ConstrainedShortestPathIntent class extends ShortestPathIntent class that expresses bandwidth as an additional intention to ShortestPathIntent
- PathIntent class extends Intent class that expresses path
