Task: Implement route() method the LandingPoint class

Task Description

This Task will...

• Give Landing Points a method to route to a connected landing point
• Prioritize using cables that send the packet to a landing point CLOSEST to the destination
  1. If multiple landing points are considered "neighbors" of the router, choose the "best" landing point
  2. If a singular landing point is connected to multiple cables, choose the cable that sends the packet to the "best" landing point
• Add the start router, cable nodes, and end router to the path

This method overrides the method from #26

1. Determine a landing point neighbor to use (random?)
2. Search for all the cables associated with that landing point
3. Choose the cable whose other endpoint is closest to the destination
4. Treat the endpoint as a router, not a landing point for routing purposes

Decision: Instead of animating directly on top of the multi-lines represented by the cables:

• Search for all landing points connected to that cable (query for cables --> associated landing points)
• Choose the landing point closest to the destination
• Route to that landing point as a straight line

Perhaps consider animating the submarine cable line differently, to distinguish it from other cables

If we figure out a way to implement that later, great -- but for now, so be it
