Game Timer

[jugglinmike]

According to the specification, the game should end after 1 or 2 minutes. We'll
get into game "screens" later on, but for now, let's make sure the moles stop
appearing and print the score.

• director.js
  • Define an endGame method on the Director prototype
  • Print the player performance information (whacCount and
    escapeCount) to the developer's console in the endGame method. You can
    use the console.log method to do this.
  • Hide all the moles (only if they are currently visible). Make sure that
    they don't get scheduled to automatically show themselves again!
  • Update the Director constructor to schedule the endGame method to
    be invoked in one or two minutes (remember: use setTimeout)

Playing through a couple times, you may notice that some moles sometimes pop
up after the game is supposed to be over. Do you know why that is? Can you fix
it?

(This is a tricky one, so here's a hint: clearTimeout is a global function
that lets you cancel code you have already scheduled to run with setTimeout.
Read the docs on MDN for more info.)
