This function is called in the main robot's onPaint(Graphics2D).

Already defined:

• bot - reference to this AdvancedRobot.
• waves - collection of Waves with properties:
  • double extent - the size of an angle covering -1 to +1 on the wave in radians
  • boolean paint - I don't always paint all my waves
  • long ctime - tick when the wave was fired
  • double velocity - the bullet speed of this wave - how fast it's traveling
  • double heading - wave's heading
  • int clockwise - +1 for clockwise, -1 for counterclockwise (widdershins)
  • int segment - which segment applies to this wave
  • Point2D.Double origin - wave's origin
• int NUM_WAVEBUCKETS - have a guess? :)
• double[number of segments][NUM_WAVEBUCKETS] waveBuckets - array of segmentation data
