Assignment 4, Question 1.
BugProgram.java

This program features three bugs: an ant, fly, and a bee. Each bug lands on the wire at a different initial position.
The ant goes onto the wire and moves towards the right.
The fly goes onto the wire and moves to the left.
The bee goes onto the wire and moves to the right until it reaches the wall and then it reverses direction.
