CST 111 Exam #1:  
"Shooting Fish in a Barrel"

Using the "Processing" PDE, write a program to do the following:

• Display a rectangular tank (or "barrel")
• A fish swims horizontally, within the barrel from left to right.
• When the fish reaches the right side, "reset" it as follows:
  • return to the left side
  • set to a random height (between top and bottom of barrel)
  • swim to the right at a random speed
• Subtract one point from score when fish reaches right side without being caught!

• At the top of the tank (somewhere near the center) is a gun.
• Clicking on the gun causes it to shoot a black "bullet" downward.
• The 'g' key also does the same thing.     SUGGESTION:   code the keyPressed() method first; it's easier!
• If the bullet hits the fish, reset the fish and add 100 points to the score..
• Deduct 5 points from score for every time the gun shoots.

EXTRA FEATURES  

• Add a second fish, which swims from right to left and has a different color.
  • Second fish has same features as first, but swims in opposite direction
    
  • Be sure to check for bullets hitting both fish (and adjust the score).
• Keep track of total number of hits & misses; display totals beneath the score.
• Add your own creature that slowly moves back and forth along the top of the barrel.
• When you click on the creature, it jumps directly to the gun position and shoots.
• Add a small house and tree, somewhere outside the barrel.
• Add a dead fish at the bottom of the barrel.
